Abstract: A solid polymer electrolyte composite membrane and method of manufacturing the same. According to one embodiment, the composite membrane comprises a thin, rigid, dimensionally-stable, non-electrically-conducting support, the support having a plurality of cylindrical, straight-through pores extending perpendicularly between opposing top and bottom surfaces of the support. The pores are unevenly distributed, with some or no pores located along the periphery and more pores located centrally. The pores are completely filled with a solid polymer electrolyte, the solid polymer electrolyte including a dispersed reduced noble metal or noble metal oxide. The solid polymer electrolyte may also be deposited over the top and/or bottom surfaces of the support.

Abstract: Universal cell frame generic for use as an anode frame and as a cathode frame in a water electrolyzer. According to one embodiment, the universal cell frame includes a unitary annular member having a central opening. Four trios of transverse openings are provided in the annular member, each trio being spaced apart by about 90 degrees. A plurality of internal radial passageways fluidly interconnect the central opening and each of the transverse openings of two diametrically-opposed trios of openings, the other two trios of openings lacking corresponding radial passageways. Sealing ribs are provided on the top and bottom surfaces of the annular member. The present invention is also directed at a water electrolyzer that includes two such cell frames, one being used as the anode frame and the other being used as the cathode frame, the cathode frame being rotated 90 degrees relative to the anode frame.

Abstract: A unitized electrolyzer apparatus for generating hydrogen gas at high pressure. According to one embodiment, the apparatus includes a pressure-containment vessel, a water electrolyzer stack, and a water supply. The water electrolyzer stack is mounted on or in the vessel and is used to generate hydrogen gas for containment in the vessel at high pressure. The water supply is contained within the vessel, the water supply being fluidly coupled to the water electrolyzer stack to provide a cathode feeding of water to the water electrolyzer stack.

Abstract: A fuel cell system including a gas recycling and re-pressurizing assembly. In one embodiment, the fuel cell system includes a fuel cell stack, the stack having an oxygen outlet and an oxygen inlet. The fuel cell system additionally includes two gas/water separator tanks, each of the tanks containing a quantity of water and a quantity of oxygen gas. Both tanks are capable of being fluidly connected to either the oxygen inlet or the oxygen outlet of the fuel cell stack. In addition, the two tanks are connected to one another so that water may be transferred back and forth between the two tanks. The system also includes a pump for transferring water back and forth between the tanks.

The system also includes a pump for transferring water back and forth between the tanks. In use, water is pumped from one of the tanks to the other until all of the oxygen gas present within the water-receiving tank is forced out of that tank and is conducted back to the oxygen inlet of the fuel cell stack.

Abstract: Cell frame for high-pressure water electrolyzer and method of manufacturing the same. According to one embodiment, radial openings in a water electrolyzer frame are provided by laminating half-frames, one or both of which contains grooves that may be formed by molding, machining or die-cutting. Another to another embodiment, radial openings are provided by laminating three or more thin frame portions, the center piece of which may include transverse slots that may be made by molding, machining or die-cutting. According to yet another embodiment, two or more frame portions are provided, at least one of which includes a recess for receiving a porous structure. The frames of the present invention can be additionally laminated to the membrane and electrode assembly, as well as the bipolar separator plate in the perimeter or seal area, comprised of the same or similar material as the frame, to form unitized electrolyzer stack subassemblies or full assemblies.

Abstract: A microwave radiation source is introduced into a fry basket within the fry tank of a deep fat fryer to reduce the cooking time of food products within the fry basket. Microwave energy is generated outside the fry tank and coupled into the fry basket by a microwave tuned transition, waveguide and antenna. Microwave chokes seal the basket top cover and microwave antenna to basket interface to confine the microwave energy to the fry basket. An electrical safety interlock prevents generation of microwave energy unless the fry basket is sealed.

Abstract: An apparatus for cooking an article is provided including a cooking chamber, a heating means for producing heated gases for introduction into said chamber for convective heating without microwave interference, and a source of microwaves for heating with microwave energy. At least one freely rotating stirring means is positioned in gas and microwave communication with the heating chamber, and is caused to rotate from a flow of the heated gases. The stirring means serves to distribute both microwave energy and the heated gases about the chamber for uniform, simultaneous convection and microwave heating. A pilotless gas source is provided which includes an initiation chamber within a combustion chamber. The initiation chamber is positioned by a microwave opaque material and includes a flame sensor which eliminates the flow of gas in the combustion chamber when no flame is present.
