摘要： Fuel cell cathodes and instant startup fuel cells employing the cathode. The cathodes operate through the mechanism of redox couples which uniquely provide multiple degrees of freedom in selecting the operating voltages available for such fuel cells. Such cathodes provide the fuel cells in which they are used a “buffer” or “charge” of oxidizer available within the cathode at all times.

摘要： A layered oxygen electrode incorporating a peroxide decomposition catalyst. The design of the oxygen electrode promotes oxygen dissociation and absorption within the oxygen electrode. The oxygen electrode has differing layers of hydrophobicity which allow chemical impregnation of the active catalyst material into the oxygen electrode where the active catalyst material is needed most.

摘要： A fuel cell utilizing parallel flow of a hydrogen stream, an oxygen stream, and an electrolyte solution with respect to the electrodes, while maintaining mechanical support within the fuel cell. The fuel cell utilizes electrode assemblies having a frame overmolded around the electrode to maintain a flow rates and low pressure throughout the fuel cell. The fuel cell is also designed to maintain mechanical support within the fuel cell while the electrodes expand and contract in response to the absorption of oxygen and hydrogen.

摘要： A hydrogen storage alloy active material for the anode of Ovonic instant startup/regenerative fuel cells. The active material includes a hydrogen storage alloy material with a water reactive chemical hydride additive, which, upon utilization of the active material in an anode of an alkaline electrolyte fuel cell, gives the anode added benefits, not attainable by using hydrogen storage alloy material alone. These added benefits include 1) precharge of the hydrogen storage material with hydrogen; 2) higher porosity/increased surface area/reduced electrode polarization at high currents; 3) simplified, faster activation of the hydrogen storage alloy; and 4) optionally, enhanced corrosion protection for the hydrogen storage alloy.

摘要： A double layered oxygen electrode impregnated with an active catalyst material and method of making. The design of the oxygen electrode promotes oxygen dissociation and absorption within the oxygen electrode. The oxygen electrode has differing layers of hydrophobicity which allow chemical impregnation of the active catalyst material into the oxygen electrode where the active catalyst material is needed most.
