The invention generates mechanical energy and electrical energy efficiently, by combining a Stirling engine and a fuel cell. To achieve this, a solid electrolyte type fuel cell FC is disposed between an air passage 35 for supplying air to a heater 24 of a Stirling engine E and a fuel passage 36 for supplying a fuel. Air and the fuel react with each other in the solid electrolyte type fuel cell FC to generate electrical energy, an off gas containing the unreacted fuel discharged from the solid electrolyte type fuel cell FC is supplied to the heater 24 of the Stirling engine E and subjected to catalytic combustion, and the resulting heat is used to operate the Stirling engine E to generate mechanical energy. The solid electrolyte type fuel cell FC is annular-shaped and so disposed as to surround the heater 24, and the heat of reaction generated in the solid electrolyte type fuel cell FC is made to act on the heater 24, thereby contributing to elevation of the temperature of the heater 24. <IMAGE> |
