A community about hydrogen and its use as a way to fight climate change.
All posts must be about hydrogen, fuel cells, or a related topic.
Posters that only attack hydrogen will not be tolerated.
Looked through the article but didn't see how much platinum was required for each cell. Given the limited amount of platinum I imagine this solution wouldn't scale well. Hopefully similar PEM systems can be created with more abundant metals.
Platinum is 100% recyclable already. It's highly unlikely this is a major problem.
The thing is it's also very rare from what I heard.
You only need grams of it per fuel cell stack. It is not much more than what is already being used in catalytic converters. So it is unlikely to be a big problem.
Thanks I wasn't aware it was that little that was needed. Guess in a fuel cell it will even have a longer life span than in a catalytic converter.
It's also harder to steal
Hold up OP. Did you downvote our friend for posting a well thought out opinion? This isn't Reddit. We don't need that here.
