How does a fuel cell work?
« on: 21/05/2013 05:30:02 »
Ryan Barthel  asked the Naked Scientists:
   
I am writing a report on proton exchange membrane fuel cells for school, and the aspect which is confusing me is how hydrogen gas is split into protons and electrons at the anode of the system.

I know it has something to do with the platinum catalyst but I cannot find anywhere why platinum is good for this. Many thanks for the response!

What do you think?
