  • 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.
