摘要： A heat pipe is installed in a generating chamber of a module being comprised of a solid oxide fuel cell or a bundle of a plurality of solid oxide fuel cells connected in parallel or series. Preferably, the heat pipe is installed across the generating chamber and a combustion chamber for burning residual fuel unused as electrochemical reaction. By installing the heat pipe as described above, the heat transfer between both the chambers are executed smoothly, and thereby it is possible to make heat uniform in the module, in starting state, normal generating state, high power output state or abnormal state of the module.

摘要： 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.

摘要： It is an object to shorten current path between an anode and a cathode in a tube type SOFC and thereby to decrease resistance. The tube type fuel cell contains a tube type electrolyte placed between an anode and a cathode, wherein an auxiliary electrode is provided over the entire region of a cell reaction region on at least one of the anode and cathode. The current path is shortened and resistance is decreased, because the anode auxiliary electrode or cathode auxiliary electrode is provided over the entire peripheral surface of the anode or cathode, and the current path in the auxiliary electrode has a greatly increased cross-sectional area.
