PURPOSE:To supply pure hydrogen to a low-temperature proton conductivity type fuel cell through the fuel reformation of fuel such as methane or the like by using a hydrogen separating film inside a reforming reaction tube. CONSTITUTION:Pure hydrogen from a fuel reformer 11 is supplied to a fuel cell(FC) 22 through a hydrogen absorbing alloy system 19 to contribute to power generation as fuel, and then water content is sent to a heat exchanger 16 to be evaporated to steam which is inputted in the reformer 11. The reformer 11 is provided inside its reforming reaction tube 13 with a hydrogen separating tube, that is, a tube formed of palladium thin film (hydrogen separating film) of 1 to 50mum thickness laid on a porous metal tube, so that the pure hydrogen (H2) may be supplied to a low-temperature proton conductivity type fuel cell through fuel reformation of fuel such as CH4, C2H6, C3H8, CH3OH or the like and power generation can be efficiently performed. |
