Galvanic cells that are designed to convert the energy of combustion of fuels like hydrogen, methane, methanol, etc. directly into electrical energy are called fuel cells.
As long as the reactants are provided, the cell will run continually.
The alkaline fuel cell is one of the most developed fuel cell technology (AFC).
Another name for the fuel cell is the Bacon cell.
Uses of fuel cell
In comparison to thermal plants, which have an efficiency of roughly , fuel cells produce electricity with an efficiency of about .
Alkaline fuel cells consume pure oxygen and hydrogen to produce electricity, heat, and potable water.
