    摘要: A complete fuel cell system (10) is described. The fuel cell system (10) comprises at least two fuel precursors (16, 18) that react to create hydrogen. A solid fuel precursor (18) can be carried in disposable fuel cartridges (100). A passive pressure control system including a dose pump (22) and a pressure equalization system (24, 300, 504) is provided to dose a liquid fuel precursor (16) to the solid fuel precursor (18) in the fuel cartridge (100). An outer wall (102) of the fuel cartridge can form a part of the passive pressure control system. The solid fuel precursor may include larger metallic particles coated by another fine metallic particles such that multiple micro galvanic cells are formed on the surface of the larger metallic particles. The fuel cell system may also include a gas buffer (40) that stores produced hydrogen that in unneeded by the fuel cell, and a water trapping mechanism (604). The fuel cell system may also have an electronic vent (46) that consumes unneeded hydrogen.

    摘要: A hydrogen generation system comprising a solid fuel that reacts with an aqueous liquid to generate hydrogen is disclosed. The solid fuel comprises first metallic particles coated by smaller second metallic particles, such that multiple galvanic cells are formed on a surface of the first metallic particles between the metals in the first metallic particles and the second metallic particles. The first metallic particles can be further covered by smaller third particles. An example of the solid fuel is hybrid particles formed by larger magnesium particles coated by smaller iron and silicon particles. The solid fuel may also include salt such as sodium chloride and/or a fire retardant such as potassium chloride. The salt may be added to the aqueous liquid instead. The solid fuel can be formed into fuel pellets, or can be suspended in a suspension agent to form slurries or gels.
