Patent ID: 7534275

Claim:
A hydrogen generator system for generating hydrogen from water split reaction, comprising: a) a pressure container having a water inlet for fluidly coupling to a water source and flowing water to a bottom of the container, and a product hydrogen outlet for fluidly coupling to a hydrogen consumer and flowing hydrogen collected inside the container to the consumer; b) a plurality of cells vertically stacked inside the container and containing a reactant compound comprising a mechanical mixture of a reactant metal and an anti-passivation material and producing hydrogen gas upon contact with water, the cells being fluidly communicative with water and hydrogen gas and stacked such that water rising from the bottom of the container sequentially activates each immersed cell to produce hydrogen gas, wherein each cell of said plurality of cells comprises a sealable internal reaction chamber for confining a selected amount of water and reactant compound therein after said cell is immersed.
