Abstract
To generate mechanical energy and electrical energy efficiently, by combining a Stirling engine and a fuel cell. A solid electrolyte type fuel cell FC is disposed between an air passage for supplying air to a heater of a Stirling engine E and a fuel passage for supplying 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 of the Stirling engine E and subjected to catalytic combustion. The resulting heat is used to operate the Stirling engine E to generate mechanical energy. The solid electrolyte type fuel cell FC is arranged in an annular-shape and so disposed as to surround the heater. The heat of reaction generated in the solid electrolyte type fuel cell FC acts on the heater, thereby contributing to elevation of the temperature of the heater.
