I don't get it.  Where is the energy coming from?  Do you still have to do electrolysis, but it just works faster with this catalyst?

Expensive catalysts still required

Interesting work. Still relies upon a precious metal catalyst within the fuel cell itself. The "P" in a PEM fuel cell is platinum. Not a metal that is cheap! If you don't mind having a fortune in precious metal rolling down the street they work great. I read from time to time that nickle catalysts are being explored within the cell itself but long term contamination is still a problem for most. Thanks for the informative article.

Yes, your car could be run on water--if you wanted to wait around long enough for electrolysis to produce enough hydrogen. This catalyst is supposed to make the process quick, but unfortunately requires too much electricity. Also oil doesn't just come from the Middle East, there are plenty of U.S. suppliers who will oppose the DoE making fuel cells recharging cheaper than buying gas. Probably end-up a military-only technology.

The problem with hydrogen as a fuel, either in a combustion engine or a fuel cell, is its intractability if not chained to a more docile atom. A plausible way to generate it quickly and cheaply, by detaching it from its tranquiliser would certainly be a great help in making it a practical fuel. However, that does not make it a primary source of energy.

What is implied by the article's claims about freedom from reliance on the Middle East is dangerously close to headlines about "How to run your car on water". I'm surprised to see a scientist quoted in an engineering publication saying things like that: could it be an attempt to justify the existence of the DoE?

Who said fuel cells were dead? DoE says it has the technology to make them work without fossil fuel freeing us from the MiddleEast.
