TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The power generator further comprises conduit(s) connecting the water vapor generator to the hydrogen gas generator and conduit(s) connecting the generator to the fuel cell. A return line is provided which directs residual water vapor and hydrogen gas from the fuel cell to the water vapor generator. The water vapor generator comprises a chamber partially filled with water, a mixture of water and alcohol, water vapor, ice, a non-fluid substance which reacts with water vapor to generate hydrogen gas, or a non-fluid substance which reacts with a mixture of alcohol and water vapor to generate hydrogen gas. At least one device is attached to the water vapor generator, the hydrogen generator or the fuel cell for causing an initial flow of water vapor from the water vapor generator to the hydrogen gas generator.Mesopump(s) (22) is provided for pumping hydrogen gas and water vapor between the water vapor generator and the fuel cell. Mesovalve(s) is provided for regulating the passage of water vapor between the water vapor generator and the hydrogen gas generator. Porous plugs are provided for impeding the flow of liquid water from the water vapor generator and allowing the flow of hydrogen gas and water vapor into and out of the water vapor generator. The fuel cell is partially surrounded by a thermal insulator. A heater (34) is adjacent to the fuel cell. A tensile membrane (32) is within the water vapor generator which exerts pressure directing water vapor from the water vapor generator to the hydrogen gas generator.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The non-fluid substance comprises a material from alkali metals, calcium hydride, lithium hydride, lithium aluminum hydride, decaborane, sodium borohydride, and/or lithium borohydride. A hydrogen generation catalyst is combined with the non-fluid substance. It is cobalt, nickel, ruthenium and/or alloys.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The water vapor generator, the hydrogen gas generator, the fuel cell and the optional conduits are formed within a polymeric block.Preferred Material: The polymeric block comprises a polyethylene, a polyimide, a polycarbonate, and/or an acrylic.
