>Why formate? Can't you get hydrogen from any acid, because that's literally the definition of an acid?
Formate releases hydrogen differently:
HCOOH >> H2 + CO2
Other acids need an electron donor to produce hydrogen. Formate reduces itself.
>"If the regeneration and reaction could be performed at 8 M rather than 3 M concentration...", why can't they?
You're getting a little over my head here, but I think there might be some solubility problems.
>"If the cell voltage could be reduced" sounds super fishy to me; isn't that just a useless wish that the elements / molecules you're working with have different properties than they actually do?
The standard electrode potential does create a minimum voltage, but usually there is considerable inefficiency.
I can't answer the other questions, except to mention that formate is very stable and easy to store.
