+徐龙珠 hello , I'm interested in what he says, how i contact you?.

[@ThatsWhenItkickedin]

transportation, portable uses, and stationary installations. In the future, fuel cells could power our cars, with hydrogen replacing the petroleum fuel that is used in most vehicles

[@a.mizrak]

Hi, could you give me your email adress, and if there is one, the company's web page? Thanks.

[@DJWRailroad]

Outstanding video overview, excellent shop location (less than two miles from the coast!), great website. These guys work out of a small metal clad building practically within walking distance to the East Coast. Hydrogen is the direction we need to go in, vs. the current, mass marketed, outdated battery technology. We're all way behind on this exceptional alternative fuel source. We started working on hydrogen fuel for our custom made boats (V8, Jet and prop ski boats) 40 years ago. Unfortunately that R&D bankrupted us. So it's great to see vids like this promoting this exceptional fuel source.

[@PragmaIndustries]

Thank you for your support.

Hello guys, I just realized that all comments were pending my approval for a while!!! Sorry about that. They are now all published and I'll answer all. Thanks for watching.

Hi, I was wondering if you guys design and manufacture the fuel cell components in house?

[@inflight1526]

I thought that heat helps the chemical reaction process. So why are you cooling it and where are you putting this heat so that it's not wasteful?

[@sampsonsunny6298]

How much voltage can be generated by 1 cell?

[@tonyjames6005]

Is this the same fuel cell used in Toyota mirai cars? If yes could you please tell me the weight of the components. I am doing my dissertation on fuel cell cars and this video helped me a lot.

[@antoniobragancamartins3165]

Hi guys, where at this model was the platinum? Was it blended with grafite?

[@ImNotOriginal1]

Hello you should make the fuel stack out of graphene. Then you can see how much better performance it would give

[@shafiqryzal6723]

Hi there may I know the overall electricity production efficiency when using the PEM Fuel Cells and have you guys incorporated nanofluids in your cooling liquid?

Your video was so cool to me but I didn't understand some details. Could you please give me some file instruction? Thank you :)

[@beforebefore]

In this type of experimental cell, it appears that the graphite plates are the actual conductive Anode and Cathode for each cell, right? Then the gold colored metal Anode and Cathode plates are the "final" contact plates for the entire stack? If this is true, then are the gaskets (o-rings) between the plates also conductive? (or is the stack compressed enough to cause intimate contact between adjacent graphite plates?) The PEM membrane... this is considered the "electrolyte"... but it is a non-chemically reactive film, but simply a material that's "porous" to the hydrogen ions, but insulates the electrons? What is the process that causes the ion to leave the hydrogen molecule? Isn't it a catalytic process? If so, where does the Platinum catalyst come into play? Are there nano-scale platinum particles embedded into the surface of the graphite plates in the gas distribution channels? Is this the process that's exothermic, or is it the recombination of O2 and the Hydrogen ions that gives off heat? (or both?) Do both Anode and Cathode undergo heating? (I'm just trying to piece together "bits and pieces" of information I've gathered from various sources.) Is there any advantage to using pure O2 as the oxidizer, instead of atmospheric "air" - which is very diluted? (such as less damage to the PEM or the Anode/Cathodes) Also, what would happen if the H2 supply had small amounts of O2 as well... would the O2 be discharged as part of the H2 "exhaust" (outlet) stream? ... or would the presence of O2 inhibit the stripping of the Hydrogen ions? What is the typical single-pass H2 conversion efficiency? Would this efficiency be increased if the oxidizer were O2, not "air"?

[@FilmPA1986]

I think your question was too revealing to their bullshit scam, that's why you didn't get a response.

[@PragmaIndustries]

@raniisc14 I agree. However, I'm not sure to be ready to make public all the secrets behind the company's state of the art technology... I kinda need to make a living out of it! BTW, we are also working on plateless and gasketless fuel cell technologies.

[@PragmaIndustries]

@azizeqab Hello, operating temperature of this fuel cell is ambient to 80°C. It is a "forced air flow" design, as opposed to "open cathode" (forced convection by fan through transversal channels) or "air breathing" design (natural convection over flat cathodes side). So air is pushed inside the fuel cell and distributed to the cells the same way that hydrogen is supplied to anodes. Cooling is achieved with a separate flow field within each bipolar plates by liquid flow.

[@chrispatrick1824]

Best his heart but seriously. I guess its a language error to call her nuts "bolts", but using the ol high carbon steel screwdriver to loosen the sticky gasket is back yard hack as they come fellas. Someone please hand that boy a nylon wedge or dead blow hammer so that I can stop cringing and try to enjoy your delightful vidi

[@mmotitaniumanode8824]

Hello sir, have you ever used titanium sintered materials?

[@PragmaIndustries]

@roshan21031988 Compression plates are machined from an aluminum bloc. Physical properties: look at properties of AU4G or 2017 aluminum type.

Thanks for the demonstration. Where can I buy proton exchange membranes?

[@Shineinpoverty]

Correct me if I am wrong, but it seems that these plates poses majical properties allowing them to work on hydrogen. Am I right?

[@istiap3468]

Hi!! I'm istia from indonesia. I'm a college student and i'm really interested with this video. By the Way, I wanna ask, how about multi stack direct ethanol fuel cell?? how the second MEA can react to the ethanol?? Would you mind to explain me? Thank you

[@lreichardt]

Very clear instruction, well done

[@PragmaIndustries]

It is a graphite compound. It is electrically conductive and chemically inert as well as being a good barrier to hydrogen to avoid cross over.

[@newageautotechnology]

So does it produce and then consume the hydrogen to make electricity?

[@tajammulkha_n6791]

If we consider PEM Electrolyzer; whether bipolar plates are in direct contact & hence complete circuit or circuit is completed by H+ ions generated at PEM?

[@uditsaxena3844]

it was crystal clear in few minutes i learned a lot from you

[@raniisc14]

good instructive video. thanks it would be further useful to demo a state of the art FC design.

[@AhmadRaza-in9er]

I didn't understood the current collector how it would work it not conencted to inner cell

[@PragmaIndustries]

Hi Daniel, air breathing design works quite well for PEM fuel cell type. Water management is a challenge though, as the air flow through the FC is high. The FC tends to dry. However this can be solved with suitable gas diffusion layers applied to electrodes (thick and hydrophobic to maintain water within the electrolyte). No scientific publication has been made by Pragma Industries on this work.

[@amilcarodinirstinghen]

How mutch a unit This

[@PragmaIndustries]

@greatimescomunity If we talk about the PEM fuel cell family type, the one presented in the video, there are a few key materials. - the electrolyte is made of a polymer film having the property of carrying hydrogen protons. - catalyst of the reaction is platinum in nanometer-size particles and is used at electrodes More details at Pragma Industries' website. Look for the "fuel cell explained" link at the bottom of the home page. Not enough characters available here to give a detailed answer.

[@facethemusic2661]

What material is the current collector made of?

[@karinenatanilupatini711]

since electrons can't pass the mea, how do the electrons in a second cell get back to the current collector?

[@PragmaIndustries]

Karine Natani Lupatini Hi Karine, in a fuel cell, electrons will move in opposite direction to the H+ ions. For example, let's start at cell N in the middle of the stack. H+ ions will migrate through the electrolyte of the cell N, from the anode to the cathode side of the membrane. Electrons will migrate from the anode of the cell N, to the cathode of cell N-1 through the conductive bipolar plate. So if will look again at what's happening at cathode side of cell N, we get H+ ions form anode N, oxygen and electrons arriving from cell N+1 = H20. Is that a little bit clearer ?

[@mdmosaddekhossen6303]

+Pragma Industries, But are not conductive bipolar plates seperated with the MEA? so how are the electrons getting transferred between those plates?

[@Jordan-ql8pv]

Electrons take the shortest path. I believe since they cannot pass through the MEA they are forced to go from the negative outer plate through whatever motor you are using and back to the positive plate on the other side of the fuel cell.

[@darkmurphyy]

Thank you! That's exactly what I have been trying to understand!

It's not a battery, fuel cell stacks produce hydrogen gas from water.

[@paulebbert2506]

It seems to need no acid nor salt, etc. (made of only stable compounds - doesn't destroy it's self).

[@rsailor971]

Why are the channels in the bipolar plates serpentine? Why are they not straight channels with straight collection manifolds on each end?

[@ThePip247]

Hi are you the same man that made the vid clip virtual hair cut ? "virtual barber shop" please please go and have a listen you sound just like lougee --thumbs up if you think so ! it`s good --------Pip

[@ChristmasEve777]

This was a wonderful learning experience! Thank you! This helped me better understand PEM electrolyzers too! That fuel cell looks like it would work as an electrolyzer with no problem. You could force deionized water into one port on the anode and collect oxygen and recycle water from the other port, diagonal from it. On the cathode side, you connect both ports to a T connector, run through a water-gas separator and collect the hydrogen. The water cooling ports would remain unused. I would LOVE to see how many LPM I could get from a stack that size!! :)

[@MinecraftSurge]

It looks like they are putting these graphite plates into PEM fuel cells and running hexo and mirai cars with it. It looks like the the fuel cell is made of like 400 plates and it's like 3 feet long, two foot wide, ect. So they use graphite plates? No platinum or anything? is this to save costs?

[@ChristmasEve777]

@@MinecraftSurge I had to watch a little clip of the video again to refresh my memory. Yeah, he didn't just use Nafion in between the graphite plates. He was putting complete MEA's in between them, which already has some platinum deposited on them. Those black squares on each side of the Nafion membranes contain carbon, platinum and I forget what else. And, the platinum is the most expensive material, followed by the Nafion.

[@PragmaIndustries]

@ThePip247 No, I'm not Luigi from the "Virtual Barber Shop" video. I had a look at it and found it quite impressive. But I'm not Luigi... sorry for the disappointment, if any. I have to say that one may think that I sound like him. I do. But Luigi has more an Italian accent. Mine is French ;-)

If I want to put my own prepared nanomaterials on the Gas diffusion layer, how to do that??

[@bertoldriesenteil1430]

Why cool? Why not just convert the unwanted heat to electricity? That would cool too.

[@PragmaIndustries]

@wayoentertainment Thanks for finding the video useful. For the liquid flowfield (for stack cooling), you've got to be careful with the pressure drop that would result from more but smaller channels. The one we designed work great because the stack is cooled at every separator plate (it was designed for research to temperature has to be the most homogeneous within the whole stack). However, it is quite common to cool down industrial stacks every 2 or 3 plates to reduce costs and size.

[@charmncute3649]

yes homogeneous flow is need but also the thermal stress on different spot in the reactor, will poke a hole on a plate.

I am interested to know what is the highest amperage you created with this cell?

[@PragmaIndustries]

Ted Wiley 160Amp @0.4V/cell is the typical max current when the fuel cell is fed with air (1.6 amp per cm² of electrode). you can get more than that if you fall under 0.4V/cell but its not very practical and not recommended for the FC health. Another option is to feed the FC with pure hydrogen. In this case, currents reach a whole new level...

[@piprichards5616]

@@PragmaIndustries Excuse me for asking a daft question, however, How do you get current from each cell to the current collector?

[@ChristmasEve777]

@@piprichards5616 Those graphite plates with all those little grooves (channels) are conductive and they reach 0.4v / cell as they deliver gasses via those grooves and make direct contact with the MEAs. Since the graphite cell plates are back-to-back, they are electrically in series, like batteries. So the 7-cell stack he made would be 0.4 + 0.4 + 0.4 + 0.4 + 0.4 + 0.4 + 0.4 = 2.8V delivered to the current collector plates on the ends.

Hi what's the purpose for the transparent layer wrapping the MEA?

[@PragmaIndustries]

The MEA is very thin, below 20 microns and is subject to dimensional variations due to water absorption/desorption. The subgaket is used to maintain external dimensions stable and also to ease handling when assembling the stack.

[@foulz2700]

Can I purchase the bipolar plates you are using in this video for academic research and if so how can l go about it?

[@gearaxis]

Do you have to heat up the PEM to 80 degree? If the PEM operates at 80 Celcius, why would it need liquid cooling??

[@PragmaIndustries]

the PEM fuel cell will have an efficiency varying around 50%. For 1 Watt of electrical power, the fuel cell will dissipate 1 Watt of heat. A powerful, yet compact fuel cell will easily reach 80°C during operation, and it will need an active cooling not to exceed its ideal operating temperature. Depending on the design, it can be air cooled or liquid cooled.

[@gearaxis]

Thanks! I'm new to PEM. Now I know that cooling system is important to PEM. And there is new membrane that can handle higher temperature
