Abstract
This invention relates to improvements in the construction of metal oxide/lanthanum nickel hydride storage batteries. A stack construction is disclosed which allows recombination of oxygen before it reaches the hydride electrode. The oxygen gas is forced to escape from the back of the metal oxide electrode where it is reduced at a catalyst electrode held at the potential of the lanthanum nickel electrode. With rapid recombination, no build-up of pressure occurs and no oxygen gas will arrive at the hydride electrode which would tend to damage it. In one embodiment, the hydride electrode is separated from the metal oxide electrode by a fuel cell-type separator. In one embodiment, a single oxygen reduction electrode is placed between two back-to-back metal oxide electrodes, and the reduction electrode is connected to the two common leads to the hydride electrodes. In a second embodiment, the reduction electrodes are pressed against or attached to the hydride electrodes.
