Hydrogen's periodic table symbol is H.
When a number follows a letter, it's showing that there are more than one atom. Example - H²O (water) two hydrogen atoms and one oxygen atom.
To stay on a fuel theme......
Natural Gas - CH⁴ , one carbon four hydrogen.
Propane - C³H⁸, three carbon eight hydrogen.
I honestly didn't know or hadn't bothered to think about this, but these posts got me looking.. Apparently (in my brief research) fuel cells operate onYou do realize you need H2 right? Not H2O, or staying on a fuel theme CH4, and C3H8. The only way you get that is splitting the H2 from the O, or 2H2 from the CH4. You need pure hydrogen
Dihyrdrogen... aka Hydrogen Molecules (not just individual atoms)
"a catalyst at the anode separates hydrogen molecules into protons and electrons, " source
so I think what @Jdc is saying, is ya gotta use H2 not just H and there is overhead there
...interesting to me anyway
