Describe construction and working of H2-O2 fuel cell.
Construction :- )One of the simplest & most successful fuel cell is hydrogen oxygen fuel cell. ii) It consists essentially of an electrolytic solution such as 25% KOH or NaOH solution, & two inert porous electrodes (like porous carbon) containing suitable catalyst. Hydrogen & oxygen gases are bubbled through the anode & cathode compartment respectively.
