A fuel gas-steam reformer assembly, preferably an autothermal reformer assembly (3), for use in a fuel cell power plant, includes a catalyst bed (2) which is formed from a cylindrical monolithic open cell foam body. The foam body is preferably formed from a high temperature material such as stainless steel, nickel alloys and iron-aluminum alloys, or from a ceramic material. The foam body includes open cells or pores (6) which are contained within the metal or ceramic lattice (4). The lattice (4) is coated with a porous wash coat which serves as a high surface area substrate onto which catalysts used in the reformer (3) are applied. The foam body has an inlet end (8) into which a mixture of fuel steam and air is fed to begin the reforming process. An inlet portion (48) of the foam body may be provided with an iron oxide and/or noble metal catalyst and the reminder of the foam body (50) may be provided with a copper, copper/zinc and/or noble metal catalyst. |
