Abstract: An electro-galvanic hydrogen generator system that has two or more anode materials; a cathode material; and an electrolyte. The electrolyte comprises a metal hydride, at least one stabilizing agent, and a solvent. Hydrogen gas is generated whenever an anode material and the cathode material are electrically connected, and the different anode materials can be used separately or in combination to control the quantity and rate of hydrogen generation. An insulating shield may be used to catch reaction debris from the anodes. A removable inert layer may cover the electrodes. The use of cell pressure may regulate the rate of hydrogen generation. The hydrogen generator may have a separate catalyst chamber, and the hydrogen generator may also function as a battery.

Abstract: An arrangement for generating hydrogen gas utilizes differential pressure to transport fuel and spent fuel components without requiring an electrically powered fuel delivery pump.

Abstract: Hydrogen is generated through the use of a fuel solution that is prepared using solid fuel component, e.g., a metal borohydride, and a liquid fuel component, e.g. water. Both of these components are dispensed in response to control signals. The solid fuel component can take different forms, including but not limited to granules, pellets and powder. Various devices, which operate in response to control signals, are disclosed for dispensing predetermined amounts of the solid and liquid components. Advantageously, this solution can be prepared, as needed, so as to obviate the need for storing and disposing of large amounts of highly alkaline fuel and discharged fuel solutions.

Abstract: The discharged fuel solution remaining after the generation of hydrogen gas from a chemical reaction of a fuel is processed. This processing substantially reduces the liquid content of the discharged fuel thereby substantially reducing both its weight and volume. Such weight and volume reduction provides a corresponding decrease in the costs of storing and transporting the discharged fuel. This technique can be used with virtually any system that generates hydrogen via a hydrolysis process. In the disclosed embodiment, the fuel for generating hydrogen is sodium borohydride and the discharged fuel in the form of a solution or slurry of sodium metaborate is spray dried into a sodium metaborate powder. Advantageously, the present invention may be used with any of a number of techniques that accelerate the process of evaporation.
