極供給空気中の酸素濃度。In phosphoric acid fuel cells, a noble metal catalyst of platinum or platinum-based alloy is used in the cell, and it is known that noble metal particles agglomerate and deteriorate in the high potential atmosphere in the acidic electrolyte of the cell. ing. Further, due to its voltage-current characteristics, a fuel cell has a property that the voltage is high in a region where the current is low, that is, a region where the load is low. Therefore, if the load falls below a certain value, the catalyst within the battery will be exposed to a high potential, resulting in a significant drop in the performance of the mold section. Until now, various means have been proposed as means for suppressing the cell voltage during low-load operation of the fuel cell. Characteristics of fuel cells include cell operating pressure, operating temperature, and oxygen concentration in the air supplied to the air electrode.

Of these, controlling the battery voltage during low loads by changing the oxygen concentration in the air supplied to the air electrode of the battery is considered the most preferable from the viewpoint of responsiveness and impact on battery performance. ing.

系統が複雑化するなどの問題点が有った。As a method for suppressing the rise in battery voltage by controlling the oxygen concentration in the air supplied to the air electrode, for example, Japanese Patent Publication No. 60-104
As shown in Japanese Patent No. 25, a method is known in which a recirculation blower is used to circulate gas having a low oxygen concentration at the air electrode outlet of the battery to the air electrode inlet to lower the oxygen concentration in the air supplied to the air electrode. This method requires a recirculation blower to return the gas at the air electrode outlet, which has a lower pressure than the air at the air electrode inlet, to the air electrode inlet. Since this blower handles high-temperature, high-pressure gas that is approximately equal to the operating temperature and pressure of the battery, it requires a special structure in terms of bearing seal structure and heat resistance, and also requires a special structure in terms of bearing seal structure and heat resistance. There were problems in terms of protection, such as the complexity of the system.

うようにするものである。The present invention focuses on the fact that exhaust gas from the combustion section of a fuel reformer is a high-pressure inert gas containing nitrogen and carbon dioxide as its main components, and directs the exhaust gas from the combustion section to the air electrode of the battery. By mixing it with the supplied air, the oxygen concentration in the supplied air is lowered, thereby suppressing the increase in battery voltage during low load operation.
