  • Patent number: 6033634
    Abstract: A hydrogen manufacturing apparatus is equipped with a plate type high-temperature shift converter (II) which has a shift reaction chamber (7) which is filled with a high-temperature shift catalyst (8) and into which a reformed gas is introduced, a cooling chamber (9) which is filled with a filler (10) for promoting heat transfer and into which a cooling gas is introduced, and a partition (6) for separating the shift reaction chamber and the cooling chamber. The shift reaction chamber has a hydrogen gas chamber (11) separated by a plate type partition (12), and the partition is composed of a porous plate (14) and a hydrogen permeable film (13) which is coated or plated thereon and which lets only hydrogen gas permeate therethrough. Thus only hydrogen generated in the shift reaction chamber permeates the hydrogen permeable film into the hydrogen gas chamber.

  • Patent number: 5082752
    Abstract: A power generation system uses fuel cells stacked via separators. Cooling plates are provided in the fuel cell stack. Passages are formed in each cooling plate for allowing raw-material-gas-for-reformation (which also serves as stack-cooling-gas) to flow therethrough and the passages are filled with reforming catalyst. An external reformer which includes a combustion section and a reforming section is provided outside of the fuel cell stack. A stack-cooling-gas-line is connected to the passages of the cooling plates for introducing the raw-material-gas-for-the-reformation (the stack-cooling-gas) into the passages. A line for gas-for-processing is connected to the reforming section of the external reformer for feeding raw-material-gas-for-processing to the reforming section. An anode gas feed line is provided for feeding to the anode the reformed gas which has been reformed through the passages of the cooling plates and the reformed gas which has been reformed by the reforming section of the external reformer.
