Hey all,
This is just a post about some questions I had regarding electrolysis and fuel cells. I know that when electricity is forced through water the water molecules split, and produce hydrogen and oxygen gas. I was wondering how things like the electrode material and how far apart they are affect the rate of reaction?
If I used zinc metal, would it be different from copper? If they are one centimeter apart, will it be faster than 5 cm apart?
I am also curious about why platinum seems to be a good choice in hydrogen fuel cells as the catalyst. I have always wondered, what makes a specific element a good catalyst -i.e. can I substitute platinum with graphite?
Cheers,
Adrian
