An on-board hydride storage system and process are described. The system includes a slurry storage system that includes a slurry reactor and a variable concentration slurry. In one preferred configuration, the storage system stores a slurry containing a hydride storage material in a carrier fluid at a first concentration of hydride solids. The slurry reactor receives the slurry containing a second concentration of the hydride storage material and releases hydrogen as a fuel to hydrogen-power devices and vehicles.

Combined on-board hydride slurry storage and reactor system and process for hydrogen-powered vehicles and devices

A microchannel device includes several mass transfer microchannels to receive a fluid media for processing at least one heat transfer microchannel in fluid communication with a heat transfer fluid defined by a thermally conductive wall, and at several thermally conductive fins each connected to the wall and extending therefrom to separate the mass transfer microchannels from one another. In one form, the device may optionally include another heat transfer microchannel and corresponding wall that is positioned opposite the first wall and has the fins and the mass transfer microchannels extending therebetween.

Devices with extended area structures for mass transfer processing of fluids

Microchannel devices and method of use are disclosed wherein a reaction microchamberis in thermal contact with a heat exchange channel. An equilibrium limited exothermic chemical process occurs in the reaction microchamber. Sufficient heat is transferred to the heat exchange channels to substantially lower the temperature in the reaction microchamberdown its length to substantially increase at least one performance parameter of the exothermic chemical process relative to isothermal operation. Optionally, an endothermic reaction occurs in the heat exchange channelwhich is sustained by the exothermic chemical process occurring the exothermic reaction chamber. Both the reaction chamberand the heat exchange channelcan be of micro dimension. Catalystcan be provided in the microchamberin sheet form such that reactants flow by the catalyst sheet. A microchannel reactorcan be formed by integrally bonding an alternating stack of thin recessed sheets wherein the recesses in the sheets define the flow paths.
