The problem with fuel cell is they are too expensive also the storage is expensive too and too heavy, i believe that hydrogen is the fuel of future but we still have to work on fuel cell and storage, thanks for the informative video 🎉

[@toddprickett6376]

There are videos on KZbin showing Hydrogen delivered via a plug in cartridge or a paste. Both of those methods would significantly improve the distribution process, as well as speeding up refueling (pull out the old cartridge, slide in a new one, and off you go). I could imagine said cartridges being sold in virtually any store.

[@eberger02]

I spoke to a bus driver who had driven hydrogen buses. For them the problem was safety. They had to install elevated pipes at the depot etc. maybe at the scale of a car it would be sufficiently safe but it didn’t sound suitable for buses at all.

[@pierreforget3357]

They should add a smell to hydrogen, just like with propane or natural gas. Like that, we would know faster if there is a leak.

[@newageautotechnology]

Thanks for explaining this to me so i could understand how it works.

[@YoutubeBorkedMyOldHandle_why]

Good explanation. Thank you. The thing about hydrogen fuel cells is that if they were perfect, they would already be ubiquitous. Gasoline engines were pretty much this 'perfect' solution, until we discovered the environmental impact of burning fossil fuels. Hydrogen fuel cells, (which I learned about 50+ years ago) are very elegant, but are likely even more harmful to the environment than gasoline, because most hydrogen is produced from fossil fuels. They have many other issues too. Unfortunately, (other than just driving less), we don't have any great solutions. Personally, I'd lean towards keeping the gasoline engines, while trying to find an economical method of producing gasoline from 'renewable' sources.

[@Makatea]

There is a pretty great solution out there: Battery electric vehicles, you should give it a try.

[@pieterpauwelbeelaerts5995]

yes, maybe an idea is to capture CO2 and combine it with H20 to produce bio fuells. Something like a Sabatier reactor, that can produce methane (CH4). If we can use solar or volcanic heat for the gas making reactor (or electric heat by wind or solar energy) wouldn't that be a great way to a CO2 neutral society?

[@saranisntnice]

What is the efficiency of the system that you have built sir?

[@toddprickett6376]

The best thing about a hydrogen economy is that it can be used for everything: ships, trains, planes, cars, trucks, homes.

[@nicoh8715]

Hey, it should be possible to run the fuel cell with air and hydrogen. If yes can you do a comparison with Oxygen/Hydrogen and Air/Hydrogen? Would the efficiency be affected? Thanks

[@NandKishor-yt6fh]

yes possible, same as with pure oxygen.

[@johnstubbe3113]

The efficiency goes up running pure oxygen because you’re not having to compress the air plus the power ratios would be higher because oxygen is Five times more powerful than air as an oxidizer

[@ronaldstewart7586]

I really want to understand how this can be efficient when you use far more electricity than what ends up at the motor. I would also like to understand how this can be safe when a byproduct is sodium metal which is highly flammable when exposed to water, which this mechanism is filled with.

[@samodomace111]

Does fuel cell use palladium and platinum for electrolyses?

[@Peter_A1466]

Your chemistry on the electrolysis side is incorrect. Sodium hydroxide is normally NOT consumed in the process. (I think you might have looked at the chemistry of electrolysis of (molten) sodium hydroxide, rather than water with dissolved sodium hydroxide. That's a totally different thing) Nice video for the rest though.

[@ELECTRONOOBS]

My chemistry knowledge might not be totally right 🧐 Chat GBT didn't help enough hahaha. Anyway I didn't what to say is consumed, what I wanted to day is that is making the water more conductive.

[@Peter_A1466]

@@ELECTRONOOBS fair enough. I think at some point you say the electrolysis of sodium hydroxide (which you more or less described), while this is just electrolysis of water. ChatGPT also answers if you make a minor error in the way you ask the question... 😬

[@richardcoppack5357]

It may be easier to store the hydrogen as methanol, which is a lot easier to transport and store. It isnt as energy dense as gasoline/petrol. Im sure we can develop simple/efficient ways to convert hydrogen into methanol.

[@darkskysteve7029]

WOW! using this in your house if you have solar panels or wind turbines would be a really cool use. if you have excess solar power->make hydrogen if not, then create energy from the stored hydrogen to supplement solar/wind. side effect=>a little pure H2O for whatever use! you could potentially use the hydrogen generated to make methanol as well to fuel your winter heating or something as well (Sabatier process). powerful stuff displayed here! I wonder if you can just use salt in the DI water, maybe with reduced efficiency...follow on vid? (please!) awesome vid...instant sub!

[@fredhether1610]

Do you make kits for gas engine. Thank you

[@oneil9615]

The full efficiency is about 25% not 60...

[@blahorgaslisk7763]

Hydrogen production by electrolysis is about 75% efficient. Hydrogen fuel cells are 40 to 60% efficient. Traditionally electrical motors are about 80%. Now if we are very generous and assume that all the components in the chain hit very high efficiency such as 80% for the electrolysis, 60% for the Fuel cell, and 90% for the motor (because someone will claim that) you get a combined efficiency of 43%. But if we de-rate the motor to 80% efficiency that turns into 38%. With more realistic and reproduceable numbers you get 75% x 50% x 80% and the efficiency is about 30%. Now if you were to include the generation of the electricity to drive the electrolysis then efficiency goes down drastically. But without doing that you can compare the hydrogen fuel cell technology with battery electric vehicles. When I looked for Lithium Ion battery charging efficiency the first answer I got was that it is ner 100% efficient, compared to lead acid batteries that are "only" 85% efficient when charging. Second link claims 99% efficiency while the third ling says it's 70%. The rest I saw claimed between 80 to 90 % efficiency when charging. Even if they are "only" 70% efficient that would still mean that a BEV has an efficiency of about 56% if the motor is 80% efficient. That is a whole lot more efficient than the fuel cell version. Another interesting thing is to look at range. One of the things that people often say is that with a hydrogen driven car you can just fill up the tank in seconds or minutes rather than have to wait for a battery pack to charge. And that's fair. But how far can you go between the fuel stops? And here hydrogen is at a disadvantage as the gas is so light. Even at a liquid state it has only about 20% of the energy density of gasoline when compared by volume. Number ripped from my far from reliable memory so take that with a grain of salt. That means the fuel tank has to be four to five times as large as the gas tank if you want to drive as far on a tank as you do on gasoline. And the tanks can't be simple constructions either. They are either high pressure tanks or they are low pressure isolated tanks. The later is most common in the tests I've seen, but they have the disadvantage that they can't perfectly isolate the hydrogen, so they are constantly bleeding hydrogen that cook off. A tank like that is likely to bleed off all hydrogen in a week or two even if the car never leaves the parking lot. Also the hydrogen that is bled off is a fire and explosion hazzard. High pressure tanks are heavy and expensive. How heavy I can't say as I haven't looked into it. But the fact that auto makers experimenting with hydrogen fuel cells usually don't use them suggests that they are not trivial to build right. Someone I talked to thought that solid hydrogen would be the solution. That is hydrogen chilled down to the degree or pressurized enough that it turns metallic. I did look into that, ignoring all the practical problems of actually doing this. And the results were not encouraging. Metallic hydrogen is not significantly more dense than liquid hydrogen. So it would be a lot of added complexity and cost for very little, if any, improvement in storage density.

[@oneil9615]

@@blahorgaslisk7763 I'm sorry I didn't read everything but you need to include gas compression/liquefaction and transportation Wich will reduce the efficiency significantly. I've worked with hydrogen (liquid and gas) and the tanks are so heavy in comparation to the mass of hydrogen that we usually say things like "the steel truc is here". For the solid state storage it's an utopia, it is indeed possible to store a lot of hydrogen in magnesium for exemple 30% in mass approximately (you need about 1kg per 100km of hydrogen) so the storage could be only 20kg of magnesium for a good autonomy. Buuuuut we need to heat up A LOT the magnesium to recover the hydrogen which is... Not efficient at all...

[@blahorgaslisk7763]

@@oneil9615 Thanks for the heads up on compression. It's easy to forget a step like that when you don't work with the media. Enginering Explained did some videos on Hydrogen and talked about the low power per volume you got with hydrogen. That and the heavy tanks for liquid hydrogen was what he concentrated on before even talking about the efficiency. If you want to see some really horrible numbers look at combustion engines running on hydrogen...

[@yakut9876]

fuel cell and electrolysis are also highly susceptible to corrosion ! the efficiency of a gasoline combustion engine ranges between ( 36 % - 42 % ) and perhaps more, this is more efficient than photovoltaic cells ( 18 % - 26 % ), for example.

If you keep exploring that route you can check Valentin Petkov's channel. He is reviewing Stanley Meyer's patents for electrolysis. As Stan mentioned, to split water in an efficient way, water has to have some resonance so molecules are excited and more prone to be split instead of brute force electrolysis. Of course you did the opposite in this experiment to get electricity, but due to the fact you are electronic savvy, Valentin's experiments should make more sense to you

You can patent stuff that doesn't work, and in this case it doesn't.

@@matteoricci9129 in Belgium there is something called capacity tax. In short, they punish people with taxes if they consume too much energy from the grid, because otherwise they have to invest in the electricity grid...

In fact that is even an argument to go for a hybrid car... and if all people in Belgium would drive electric cars at this moment, the electricity grid would go down, they warn.

@@pieterpauwelbeelaerts5995 fancy that, in Italy, there was something like that but to improve use of heat pump they removed this tariff for houses, I checked the annual uses of electricity and in Italy is in decline, maybe a 5% over 10 years, so Italian electric grid would be able to cope at least for the first 4 or 5 years of adoption. Hydrogen still uses more electricity than just charging a car, so it will only increase the amount of electricity needed, I don't see it as a solution. Hybrid is a good step in the right direction, and it was a good choice when there are no other alternatives, but you can consider that electric cars are a better step in the right direction, better still no car at all. everybody willing to do these steps will do it depending on his condition, but here we need to check the claims, like what amount of hybrid: - mild (regen breaking and slow speed) is just an ice car that uses less petrol, long therm is not going to solve anything. -plug in could be great, if you use them right.

When you learn the center field of a magnetic force you won't be doing it that way. First off you need to use the inductive properties of copper in the water in a saw tooth wave form at the correct frequency, not a sign wave.

It's a Bad Idea: Hydrogen-Fuelcell-Cars are horribly inefficient. Today, nearly all hydrogen comes from transformig fossil fuels, especially gas. For it to be climate-neutral, you'd have to make it by electrolysis from renewable energy instead. That requires several times more electricity than needed to move a Battery-Electric Vehicle. Plus the conversion losses of the fuelcell. You also drive around in a car with the same gas the Hindenburg was filled with, but with 700 bars of pressure. And finally you regularly need to change the special HEPA-filters of the fuel cell, which also a lifespan significanly lower than the car. The only maintainance items related to the propulsion system of a BEV are cooling liquid and differential oil.

Hydrogen is complete garbage, as it is a worse version in every aspect of the core product it is made from. Hydrogen is made from CNG, which is almost the same thing, but the conversion costs about 60% of the energy of the base CNG. CNG in its pure form is easier to store (lower pressure and lower container penetration) and is already widely used in industrial, home appliance and automotive applications. Converting a car to hydrogen is far more complicated than CNG as it demands lower compression and more temp resistant materials. Making a hydrogen car costs $20k to have a 100kw fuel cell, meanwhile you can convert any road car TODAY to run on CNG for 1000$.
