Let me try to explain this one more time. Fuel cells are not charged up. Batteries and capacitors are charged up by storing electrons.

Fuel cells operate buy consuming fuel like a gas engine or gas turbine. The fuel is oxidized by oxygen (in most cases), and the oxygen reduces the fuel. It is called an oxidation reduction reaction. It does not store electrons like a battery.

Hydrogen reacts with oxygen to form water and free electrons.

Formic acid or formates react with oxygen to form water and CO2, or cabonic acid, or KHCO3, potassium bi-carbonate. The hydrogen is released from the formic acid/formate molecule and its oxidation with oxygen produces water and electrons (power). The carbonate (water plus CO2 in the liquid phase) can be recycled to an MVTG ERC to make more formate/formic acid fuel.
