  • Apparatus for the storage and conversion of energy
    Patent number: 5316643
    Abstract: A process and an apparatus for the storage and the conversion of energy hng a H.sub.2 /O.sub.2 /H.sub.2 O system by switching the mode of operation electrolytic/fuel cell reaction, with a cell being utilized which is composed of an anode compartment, a cathode compartment and an ion exchange membrane as the electrolyte. Bifunctional oxidation electrodes are utilized as electrodes in the anode compartment so that during electrolytic operation oxygen is formed and during fuel cell operation hydrogen is oxidized and with a bifunctional reduction electrode also being utilized in the cathode compartment so that during electrolytic operation hydrogen is formed and during fuel cell operation oxygen is reduced.
