activated carbon Answered

could someone use activated carbon to produce hyrdogen out of water extremely fast because of the huge amount of surface area? Or would that not matter?

I'm assuming you mean via electrolysis. Wouldn't it make more sense to use, you know, a conductor?

From what I've played with, its little granules. Powder form would be silly, its famous for its huge surface area for its "large" (4mm?) size. And what does ss have to do with this?

1 teaspoon of AC has about the same surface area as a football field. I think they use it in super caps

. I'll guess that the H2 will quickly fill the empty spaces in the AC and wipe out any advantage the larger surface area might have.

I don't think the surface area helps, because I don't think the electrode surface area is a limiting factor in electrolysis...

Where would the hydrogen come from?
