PROBLEM TO BE SOLVED: To simplify module structure, reduce the number of constituting members and improve output density by forming a fuel chamber between a top plate and a tube plate arranged within a module main body surrounded with a heat insulating material, and installing a reaction tube composed of plural cell tubes so as to pass through the tube plate and face openings of both ends to the fuel chamber. SOLUTION: A cell chamber 10a of a module main body 10 is heated to working temperature, fuel gas 20 such as hydrogen is supplied from a fuel introduction pipe 16, and air 22 of an oxidizing agent gas is supplied from an air supply pipe 19. The fuel gas 20 supplied through the fuel introduction pipe 16 flows in a cell tube 15 from an opening 15a opened in the fuel chamber 13, is used in reaction, exhausted from an opening 15b of the other end, and flows in a cell tube 15 from an adjacent opening 15a. A supply tube of fuel or air is made unnecessary, the number of module constituting members can be reduced, and as a result, the number of seal components and current collecting components can be reduced. |
