hydrogen-oxygen fuel cell may have an acidic or alkaline electrolyte. The half-cell reactions are To maximize the power per unit mass of an electrochemical cell, the electronic and electrolytic resistances of the cell must be minimized. Since fused salts have lower electrolytic resistances that aqueous solutions, high-temperature electrochemical cells are of special interest for practical applications. High temperature also allow the use of liquid metal electrode, which make possible higher current densities than solid electrodes How many grams of water is produced in the cell if 2 Faradays of charge is derived from the fuel cells
