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.

A back fire (an abnormal combustion) of the burner is prevented, the module is uniformly heated, and a secure short-time start is achieved, by cooling the fuel side burner (6) so as to adjust temperature. Further, a combined efficiency of the module is improved by utilizing the recovered surplus heat.

摘要： In a solid oxide fuel cell, the nonuniformity of temperature distribution in the axial direction of a solid electrolyte, the decrease in cell performance caused by a decreased effective cell reaction area, and the damage to cell due to thermal stress generated by a temperature difference are restrained. A reforming catalyst is provided in a high-temperature portion on the anode side to cool the high-temperature portion by means of heat absorption of reforming reaction, or a combustion catalyst is provided in a low-temperature portion on the anode side to heat the low-temperature portion by means of heat generation of combustion reaction, or both of the catalysts are provided, by which the occurrence of variations in temperature in a cell reaction region of anode is prevented. In addition, an air flow from an air introduction tube of cathode is branchingly sprayed so that a cooling effect is produced in the high-temperature portion, by which an effect of restraining the variations in temperature can further be increased.

Accordingly, gas tends to flow through the inner portion of the power generation module, a gas flow rate is quickened, and it is possible to uniformize a molar flow rate of the fuel and the air supplied to the fuel cell, even in a state in which a temperature distribution of the module is not uniform within the power generation module.
