  • In various embodiments, the present disclosure provides a layered metal-air cathode for a metal-air battery. Generally, the layered metal-air cathode comprises an active catalyst layer, a transition layer bonded to the active catalyst layer, and a backing layer bonded to the transition layer such that the transition layer is disposed between the active catalyst layer and the backing layer.
  • This patent describes a battery composed of methanol/air fuel cells which in turn are composed of a cathode, and anode and a CO/sub 2/-permeable anion exchanger membrane as electrolyte, wherein a plurality of cathodes and anodes are in a parallel arrangement in a common cathode compartment and anode compartment, respectively.
  • A fuel cell power plant for producing electricity uses pressurized reactants in the cells. The air is compressed by compressor apparatus which is powered by waste energy produced by the power plant in the form of a hot pressurized gaseous medium, such as the exhaust gases from the cathode side of the cells. For example, the compressor apparatus may comprise a compressor and a turbine which are operably connected. The exhaust gases from the cathode side of the cell are delivered into the turbine which drives the compressor for compressing the air delivered to the cells. 19 Claims, 4 Drawingmore » Figures.« less
  • A fuel cell power plant for producing electricity uses pressurized air and fuel in the cells. The air is compressed by compressor apparatus powered by waste energy in the form of hot pressurized gases including hot pressurized steam produced by the power plant. In one embodiment the compressor apparatus includes a turbine operably connected to a compressor, and hot pressurized gases produced by the power plant flow into the turbine thereby driving the compressor. The steam is generated by heat from the fuel cells, passes through the fuel cells adjacent the cathode electrode thereof, and is delivered into the turbinemore » along with the other gases.« less
  • An internal combustion engine is described that has an auxiliary monopropellant fuel supply for operation where reliance on atmospheric air for support of combustion would be undesired or not feasible. The auxiliary monopropellant fuel system includes a fuel selector valve for disconnecting supply of hydrocarbon fuel and an air cutoff valve for closing the engine cylinder air intake.
