How can I prove nickel to be a catalyst in a fuel cell using a pretty simple experiment?

recover the nickel.

[buckminsterfullerene]

also a catalyst is supposed to speed up the process of breaking apart water molecules producing oxygen gas and hydrogen gas.  prove that the process is actually faster and more efficient then if done without a catalyst.

so have you tried nickel as the catalyst in the PEM fuel cell?  if so how did it work?

Thanks pi. I'll do that.
