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.

The present invention provides a fuel cell power system and a power generating method in which the rise of concentration of water vapor and carbon dioxide in the direction of the anode gas flow is controlled to enhance the electromotive force in the downstream region of the anode gas flow, thereby improving the power generating efficiency. A mixed gas of a hydrocarbon and water vapor and/or carbon dioxide or a reformed version of said mixed gas having an oxygen atom/carbon atom ratio (O/C ratio) of 2 or higher is supplied from a spot upstream in the direction of the anode gas flow while a hydrocarbon or a mixed gas of a hydrocarbon and water vapor and/or carbon dioxide having an O/C ratio of lower than 2 is supplied supplementally from a spot downstream, and the gas supplied supplementally from the downstream side is reformed by making use of water vapor and carbon dioxide generated by the electrochemical reactions upstream of the anode gas flow and is utilized for power generation.

The vehicle-use power supply management apparatus includes a first function of detecting start of any of electrical loads mounted on a vehicle, a second function of detecting a battery voltage, a third function of determining whether or not load restriction should be performed on the basis of the battery voltage detected by the second function, a fourth function of making a determination of whether or not the detected electrical load can be applied with load restriction, and a fifth function of applying load restriction to the detected electrical load if a determination result of the third function and a determination result of the fourth function are affirmative. The third function is configured to make an affirmative determination if a drop of the battery voltage immediately after the start of the detected electrical load is larger than a predetermined value and the duration of the drop exceeds a predetermined time period.

In a fuel cells power generation system provided with a power generation module having a plurality of fuel cells, the structure is made such that a cross sectional area of at least one of a fuel flow path and an air flow path is larger in an inner portion of the power generation module and smaller in an outer portion thereof. 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.

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.
