Abstract:
1. A fuel cell system comprising: a reaction vessel having a catalyst carried in the vessel for promoting an endothermic reaction, the reaction vessel being constructed and arranged to allow endothermic reactants to be charged into the vessel, and further comprising at least a first and a second heat exchanger device spaced apart from each other and carried within the vessel, and wherein the first and second heat exchanger devices are constructed and arranged to be independently controlled from each so that heat transferred by the heat exchanger devices to the catalyst, and the temperature of the catalyst, may be varied at different locations within the reaction vessel corresponding to the location of the first and second heat exchanger devices, and wherein the reaction vessel comprises a plurality of parallel substrates, each of the substrates having a first and a second surface, and wherein the first and second surfaces are located on opposite sides of the substrate, and an endothermic reaction catalyst overlying the first surface, and an exothermic reaction catalyst overlying the second surface, and wherein each of the substrates is constructed and arranged to transfer heat from the second surface to the first surface.
