A mount member () has a contact surface () touching the bottom surface of an LED module () and protrusions () protruding from the periphery of the contact surface () in the thickness direction of the LED module () and regulating sliding motions thereof. A fixing member () made of a resilient, plate-like member comprises an opposing pair of flat portions () near the contact surface () of the mount member () and flat tabs () projecting from the flat portions () toward the contact surface () touching the upper surface of a substrate (). The flat portions () of the fixing member () are fastened to be lower than the top surface of the substrate () of the LED module (). Thus, elastically deformed areas extending from the fastened parts of the flat portions () through the flat tabs () press the substrate () into the mount member ().

A temperature adjustment member is arranged to control temperature of a reformer independently of temperature of a fuel cell module. The reformer is structured as a three-fluid heat exchanger into which a fluid is introducible whose temperature is higher or lower than exhaust-gas temperature of the fuel cell module. Then, the temperature of the reformer is controlled independently of operation temperature of the fuel cell by introducing the higher-temperature or lower-temperature fluid into the reformer. Also, a high-temperature or low-temperature gas is mixed with the module's exhaust gas, thereby adjusting temperature of the exhaust gas itself. This also controls the temperature of the reformer independently of the operation temperature of the fuel cell.
