Abstract:
1. An electric power generating apparatus comprising: a fuel gas supply source for supplying fuel gas; an air supply source for supplying air; an external reformer having a reformer section to be supplied with the fuel gas; a fuel cell stack having an electric power generating cell section to be supplied with the fuel gas reformed in the reformer section of the external reformer; a heat exchanger section disposed on the external reformer for heat exchange between the air supplied from the air supply source and the reformer section, wherein the heat exchanger section is configured to allow the air, passing through the heat exchanger section, to be supplied to the fuel cell stack to perform heat exchange between the air and the fuel cell stack; and an exhaust gas combusting section located directly in contact with the electric power generating cell section of the fuel cell stack to permit unburned fuel gas, supplied from the electric power generating cell section, and the air, supplied from the air supply source, to be mixed and combusted to achieve heat exchange with respect to the fuel cell stack.
