This could have major negative implications for platinum mines in South Africa such as Amplats, Implats, Northam Platinum, Royal Bafokeng Platinum, Ivanhoe Mines etc.

Well that was really informative. Daniel raises a valid point too at 1:05:12 regrading combusting H2 vs electro-chemical energy extraction as combustion will still create that familiar smog we see around the major cities. Just wondering though recently I've heard about the use of graphene flakes with halogen coated edges, particularly iodine as an efficient and cheaper catalyst, is there any investigation at SLAC pursuing this too?

Try applying a high frequency pulse-voltage to resonate with the electron's movement around the nucleus to increase efficiency.
@Kalumbatsch7 жыл бұрын
And what frequency would that be?
@josidasilva55157 жыл бұрын
Since we are trying to resonate with the electron circulating the nucleus, it must be a multiple of the time x/t. Speed of the electron = 2.2*10^6 m/s divided by the elliptical distance traveled. Use the radius of hydrogen atom to calculate the distance: 2.5x10-11 m. Given the variables it will be trial by error.
@Kalumbatsch7 жыл бұрын
The first problem with that is that the electron doesn't circle around the nucleus, the second problem is that you don't even know what you're trying to do.
@josidasilva55157 жыл бұрын
Quantum mechanics is still in its infancy, therefore not appropriate to explain the efficient use of energy to resonate with existing frequencies.
@Kalumbatsch7 жыл бұрын
No. Quantum mechanics is not "in its infancy", it's the most precisely tested theory in the history of science. You won't build better fuel cells by making stuff up.

See i thought the fuel cell was used to split water into oxygen and hydrogen to be used in a combustion engine. But this suggests doing the opposite and achieving a current. I'm so confused 😕

There has been a similar reaction in terms of heat produced with common water or even salt water toward what has been traditionally thought of as cold fusion [Pons and Fleischman experiment resulting in heat energy using palladium].

Surprised to find that in late 2019, palladium is about $60,000/kg (about 2x the cost of platinum per kilogram). I’m excited to see what he says when I get to that part of the lecture Edit: around 17:30 he talks about platinum is electrochemically the best, and his analysis rules out palladium (worse performer at double the price)

You mean in the cathode? If so, peroxide formation might lead to corrosion of the catalyst and also degrade the membrane thus lowering the overall efficiency. That's why 4-electron pathway is preferred for ORR.
