Abstract:
1. A solid oxide fuel cell power generating apparatus, comprising: a solid oxide fuel cell unit having a solid oxide substrate, a porous cathode electrode layer formed on one surface of said substrate, and a porous anode electrode layer formed on the other surface of said substrate opposite from said one surface; a wall structure forming a housing section for housing said solid oxide fuel cell unit mounted in a vertical position; a supply device for supplying air and fuel to said solid oxide fuel cell unit from said housing section; and a combustion device for heating said solid oxide fuel cell unit by combusting an exhaust gas exiting from a lower end of said solid oxide fuel cell unit in a space below said housing section, wherein said supply device supplies a mixture gas containing said air and said fuel to each of said solid oxide fuel cell units from an upper end thereof, and said wall structure having an electrically insulating porous layer formed on a lower surface of said housing section, and wherein said exhaust gas is supplied to said combustion device via the electrically insulating layer.
