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: Systems and methods are provided for generating hydrogen gas using a catalyst or reagent and a boron hydride compound. The preferred hydrogen generation system includes a fuel cartridge and a hydrogen generation system balance of plant (BOP) module. Solid fuel is stored in individual fuel packets in a fuel chamber, and converted into a fuel solution. Fuel is pumped to a reactor where it produces hydrogen and borate. The hydrogen and borate product exit the reactor and are deposited in a hydrogen separation chamber separated from the fuel chamber by a moveable partition. Hydrogen is separated by a membrane and exits the generator. As fuel is consumed, the movable partition is disposed toward the fuel chamber and the borate product is deposited on one side of the movable partition. The controls are preferably contained in the BOP module.

Abstract: Purge systems and methods are disclosed for flushing unreacted materials and byproducts from a reactor. In one embodiment, the reactor houses a hydrogen generation catalyst and the system comprises a hydrogen generation fuel cartridge containing a reservoir that stores water which may be recovered from the exhaust of a fuel cell. The reservoir may comprise a flexible bladder or a piston-type configuration. Water is delivered from the reservoir to flush the reactor of any residual fuel and/or byproducts.

Abstract: A packaging system and method are disclosed for delivering a solid fuel component in pre-measured quantities for hydrogen generation.

Abstract: A spring finger EMI gasket is disclosed in which portions of its finger parts are so formed that they can be completely flattened with negligible permanent set. Thus when used in a seam, they can be flattened to provide broad are a metal-to-metal contact for low electrical impedance across the seam, while at the same time serving as a positive mechanical stop. In its preferred embodiment, when the seam is disassembled, the tips of the finger parts press firmly against one of the surfaces of the seam so as to resist snagging, a frequent cause of damage to spring fingers.
