Patent ID: 8691472

Claim:
A reservoir assembly comprising: a first cellular component interconnected with at least a second cellular component, the interconnected cellular components arranged together to substantially fill an available device space in a device; one or more end caps coupled to a portion of the first or the second cellular components; one or more internal ports, each internal port fluidly connecting the first interconnected cellular component to at least the second interconnected cellular component; one or more external ports for adding or removing a fluid from the reservoir, wherein the one or more external ports are positioned in one or more of the cellular components or end caps; and a fuel storage material disposed within one or both of the first cellular component or the second cellular component; wherein the fuel storage material comprises a composite hydrogen storage material that includes metal hydride particles mixed with a binder; and wherein the reservoir assembly is coupled with the device; and wherein the device includes at least one fuel cell that includes an anode, a cathode, and an ion-exchange membrane; and wherein the reservoir assembly is configured to supply a fuel to the anode, and further including a pressure regulator configured to regulate a pressure of the fuel supplied to the anode, wherein the pressure regulator is integrally mounted into a wall of the reservoir assembly.
