BECAUS they contain IONS which can transfer electrons which speed up rusting or oxidation!

Yea sure, You just have to know that hydrogen is a better fuel because the product of its combustion is water which isnt a pollutant advantages are that it will conserve natural resources and doesn't cause pollution. You just have to know the name Uranium-235 is used as a fuel cell. The electrode is a big topic. For the hydrogen one in supplement they have already said it. Anything I missed?
