High power density regenerative fuelcell for peak power

摘要

Low capacity and high power density electric fuel cell which electrolyzes water in the charging phase to produce hydrogen and oxygen used, as reactants in the discharging phase, which fuel cell (2) comprises an ion-ex­change membrane (3), separating two compartments, said compartments containing gas evolving positive (11) and negative electrodes (7) respectively for the evolution of oxygen and hydrogen during the charging phase and for recombination of the same to produce water during the discharging phase, as well as means for the circulation of said water in a spray form.
