Abstract
A thermally actuated hydrogen secondary battery which comprises a porous anode having a thermally actuated anode-active solid reversible hydrogen-containing inorganic compound which deintercalates hydrogen ions (H.sup.+) in a discharge cycle when exposed to thermal energy and having a first porous catalytic oxide film on a side thereof capable of converting hydrogen ions into hydrogen molecules in a discharge cycle and having a second porous catalytic metal film on another side thereof capable of converting hydrogen molecules into hydrogen ions in a charge cycle; a porous cathode having a hydrogen ion-intercalatable cathode-active material which intercalates hydrogen ions (H.sup.+) in a discharge cycle when the anode is exposed to thermal energy and having a first porous catalytic metal film on a side thereof capable of converting hydrogen molecules into hydrogen ions in a discharge cycle and having a second porous catalytic oxide film selected from the group consisting of ruthenium dioxide, rhenium dioxide and iridium dioxide on another side thereof capable of converting hydrogen ions into hydrogen molecules in a charge cycle, said first porous catalytic metal film on said porous cathode facing said first porous catalytic oxide film on said porous anode; and a porous solid electrolyte between and within the porous anode and the porous cathode, said porous solid electrolyte containing at least one gas selected from the group consisting of hydrogen and helium for the diffusion of hydrogen molecules between the anode and the cathode, said porous solid electrolyte being a polymer complex of trifluoromethane sulfonic acid with a linear polymer.
