  • Patent number: 6969562
    Abstract: A hydrogen-containing gas suitable for use in a fuel cell, especially in a proton exchange membrane fuel cell, is produced from a digestion gas (b) yielded in methane fermentation of organic matter (a), and is then supplied to the fuel cell to generate electricity. A fuel cell power generation method comprises a methane fermentation step (A) for subjecting organic matter to methane fermentation, a pretreatment step (B) for pretreating digestion gas yielded in the methane fermentation step, a hydrogen production step (C) for producing hydrogen-containing gas (c) from the gas which has been pretreated in the pretreatment step, and a fuel cell power generation step (D) for supplying the hydrogen-containing gas produced in the hydrogen production step to a fuel cell to generate electricity.
