摘要： Systems and methods for hydrogen generation based on the hydrolysis of a solid fuel are disclosed. The hydrogen generator comprises a fuel chamber for storing a solid chemical hydride, a chamber for storing a liquid reagent, and a liquid distributor disposed within the fuel chamber. The contact between the solid chemical hydride and the liquid reagent produces a substantially fluid nongaseous product and hydrogen gas. The liquid distributor is configured to move through at least a portion of the substantially fluid nongaseous product within the fuel chamber.

摘要： Systems and methods are provided in which a fuel cell purge cycle recaptures fluid material such as water and hydrogen from an electrode of a fuel cell and can recycle the hydrogen to the anode, leading to improved fuel cell efficiency with minimal parasitic load. Pressure fluctuations of a hydrogen generation system may be integrated with the fuel cell purge cycle to recycle hydrogen to the fuel cell and water to the hydrogen generation system.

摘要： Systems and methods are provided for hydrogen generation utilizing two or more liquid fuel components, using a fuel delivery system comprising a single pump. Advantageously, a single reversible cycle pump is used to deliver two or more fuel components of a fuel mixture in desired proportions to a mixing zone, reaction zone, or reaction chamber of a hydrogen generation system, while reducing the number of active elements required for fuel delivery and flow control of multiple fuel components. Alternatively, a unidirectional single or duel feed pump co-operable with flow control means comprising a valve provides for delivering first and second fuel components in desired proportions. Control of the pump speed, and duty cycle of the pump in continuous or pulsed modes, provides for delivery of first and second fuel components in desired proportions, to control hydrogen generation, and to provide for dilution, mixing, and flush cycles, using a single pump. A control system provides for control of the pump and/or valve, responsive to external or system conditions.

摘要： Hydrogen storage fuel compositions comprising a mixture of at least one chemical hydride compound and at least one compound, polymer, carboxylic acid or salt that acts as a water surrogate source, and methods for thermally initiated hydrogen generation from fuel compositions, are disclosed. The water surrogate source/chemical hydride compositions are preferably solids, and may be powders, caplets, tablets, pellets or granules, for example. The water surrogate source/chemical hydride compositions may comprise alternating layers of the chemical hydride and of the water surrogate source.
