摘要:
A device (100) includes a case (110) having a surface (115) with a perforation (116) and a cavity (113). A membrane (120) is supported by the case (110) inside the cavity (113) and has an impermeable valve plate (135) positioned proximate the perforation (116). The membrane (120) is water vapor permeable and gas impermeable and flexes responsive to a difference in pressure between the cavity (113) and outside (122) the cavity to selectively allow water vapor to pass through the perforation (116) into the cavity (113) as a function of the difference in pressure.
摘要:
A power generator (100) is formed with a container (110) adapted to hold a hydrogen generating fuel (130). A valve assembly has a valve plate (112) with a border less than a border of the container (110). A fuel cell (114) is laterally disposed outside and around the valve assembly having a lateral width that fits within the border of the container (110). A cover (115) is adapted to mate with the container (110) and enclose the valve plate (112) and fuel cell (114).

摘要:
A hydrogen producing fuel comprises a chemical hydride (715) and metal (705) hydride. In one embodiment the chemical hydride (715) evolves hydrogen spontaneously upon exposure to water vapor, and the metal hydride (705) reversibly absorbs/desorbs hydrogen based on temperature and pressure. The hydrogen producing substance may be formed in the shape of a pellet (100) and may be contained within a hydrogen and water vapor permeable, liquid water impermeable membrane (520).

摘要:
A power generator (700) includes a cavity (712) to accept a hydrogen producing fuel cartridge (110). A channel (715) is coupled to receive hydrogen from the fuel cartridge. A manifold (720) is coupled to the channel to receive hydrogen from the channel, the manifold having an opening (722) to receive oxygen and water vapor, the manifold being positioned to provide the water vapor to the cavity (712). An array of fuel cell membranes (730) is supported by the manifold (720) to receive hydrogen from the manifold and oxygen from the opening (722) in the manifold.
