摘要： PROBLEM TO BE SOLVED: To uniformly mix reformed gas with a CO selective oxidizer without causing increase in power consumption. SOLUTION: The polymer electrolyte fuel cell power generation system is constituted by having a hydrogen production system 1 including a reforming reactor 3 which forms the reformed gas containing hydrogen by using raw material gas, air, and water or steam as raw materials, a CO shift unit 4 which makes CO contained in the reformed gas react with steam, a CO selective oxidizer 6 which reduces CO concentration in the reformed gas passed through the CO shift unit 4, and an auxiliary combustor 19 which recovers heat by performing combustion treatment of an anode exhaust gas of the fuel cell, and a solid polymer fuel cell 2 which generates electric power by using the reformed gas as the fuel passing through the CO selective oxidizer 6. A gas supply tube (for auxiliary combustion exhaust gas) 27a for selective oxidization from which a part of combustion exhaust gas in the auxiliary combustor 19 is fed, or a gas supply tube (for cathode exhaust gas) 29a for the selective oxidization from which cathode exhaust gas exhausted from the solid polymer fuel cell 2 is fed is connected to the CO selective oxidizer 6.

摘要： PROBLEM TO BE SOLVED: To appropriately cancel abnormality, corresponding to an abnormal cause by properly determining the abnormal cause of a fuel cell power generation system.
SOLUTION: If voltage reduction of a fuel cell is voltage reduction of the cell (S3) as a whole, when a physical quantity correlated to an anode gas flow rate is less than a set value (S4), the voltage reduction of the fuel cell is determined to be caused by the lack of the amount of hydrogen (S5), when the physical quantity correlated to the anode gas flow rate is larger than the set value (S4); and when the anode gas temperature is lower than the set value, it is determined to be caused by the lack of humidification of reformed gas (S8, S9), when the anode gas temperature is higher than the set value, it is determined to be caused by CO poisoning (S8, S12). In any of the cases, the load current of the fuel cell is reduced (S6-S13) and a command for increasing the amount of hydrogen of the reformed gas corresponding to each cause (S7), a command for raising the anode gas temperature (S11) or a command for reducing the CO concentration of the reformed gas (S14) is outputted.

A gas suction port 6 is disposed on the piping having position relation to face the feed nozzle, and inert gas is supplied from the feed nozzle, while inert gas is sucked from the gas suction port, so that a gas curtain 23 is generated between the gas discharge sparger and the gas suction port. The gas discharge sparger communicated with the feed nozzle is disposed along a circumferential part of the piping, and the gas suction port is disposed to have position relation to face the feed nozzle. The diameter of the gas discharge sparger and the gas suction port is set to be larger than the diameter of the piping.
