摘要： PROBLEM TO BE SOLVED: To continue the operation of a fuel cell system while performing a process of reducing an abnormal voltage in case of detection of the abnormal voltage of a power generating cell. SOLUTION: When an abnormal voltage drop is generated (S6) at any of the power generating cells 200, a prescribed process is carried out in compliance with a period continued thereof, namely, when the continued period of the abnormal voltage drop exceeds t2, a process of reducing abnormal voltage is carried out (S12). More concretely, the pressure of flowing gas is increased, a time interval for exhausting off-gas from a hydrogen circulation system is shortened, and an exhaustion volume is increased. When the abnormality is not eliminated by the above process and the continued period exceeds t3, an upper limit value of an output is lowered (S14). When the continued period exceeds t4, the upper limit value of the output is further lowered (S15). When the continued period exceeds t1, the operation of the fuel cell system is stopped (S19).

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system by which retention of water in a fuel gas passage within a fuel cell is removed and prevented.
SOLUTION: A control circuit 50 closes a valve 231 at a discharge, and waits until a stand-by reference time Timepref generally required passes to attain a target pressure Piref, then determines whether a pressure Pi at the inlet of a fuel offgas circulating pump which is detected by a pressure sensor 54 at the inlet of the fuel offgas circulating pump is less than the target pressure Piref or not. The control circuit 50 opens the valve 231 at the discharge when it determines the pressure Pi at the inlet of the fuel offgas circulating pump is less than the target pressure Piref. As a result, the pressure of a fuel offgas draft tube 23 from a discharge 12 of the fuel cell FC to the fuel offgas circulating pump 24 becomes lower than a pressure within the fuel cell FC, and a big difference in pressure is generated between both pressures, by which moisture retained at the fuel gas passage within the fuel cell FC and moisture adhered to the electrode surface of a cell is moved and removed.

摘要： PROBLEM TO BE SOLVED: To secure a brake force for deceleration while maintaining a preferable state for a fuel cell in a power system which is equipped with the fuel cell and performs regeneration at deceleration.
SOLUTION: When all the regenerated power of a driving motor can be stored in a secondary battery, a hydrogen pump is operated by a low output mode (S104). When all the regenerated power can not be stored in the secondary battery and in the case, if the hydrogen pump is driven by a high output mode, the sum of chargeable power to the secondary battery and the consumption power by the hydrogen pump exceeds the regenerated power of the driving motor (S108), the hydrogen pump is driven by the high output mode. Then, the target charging power Pb of the secondary battery is made as a power which is obtained by subtracting a power Ph consumed excessively by the accelerated speed of the hydrogen pump from the regenerated power Prg1. A part of a power Ph of the power Prg1 generated by the driving motor is supplied to the hydrogen pump and consumed by the hydrogen pump.

摘要： PROBLEM TO BE SOLVED: To provide a fault determination apparatus capable of improving the fault detection accuracy of a fuel cell system. SOLUTION: A fuel circulatingly feeding system is determined for abnormality in sealing in consideration of fuel gas leakages specific to the fuel cell system. The fuel gas leakages specific to the system include the permeation of a fuel gas of very small quantity through the electrolyte membrane of the fuel cell, the permeation of the fuel gas of very small quantity produced by the material composition forming a fuel gas supply source and a fuel gas pipe, and the discharge of the fuel gas following a fuel gas purge control. In consideration of these leakages, the apparatus determines whether a fault in sealing occurs in the fuel circulatingly feeding system or not (namely, whether a fault occurs in a gas passage or valves installed in the gas passage) (step S3 → step S4).

摘要： PROBLEM TO BE SOLVED: To inhibit the occurrence of the reformed gas by the vapor of excessive reformation fuel caused by the response retardation of the evaporator without reduction in energy efficiency. SOLUTION: The reformed fuel from the reformed fuel tank 6 is heated at the vaporizer 2 and the reformed fuel from the vaporizer 2 is caused by the reforming reactions in the reformer 3 to generate the reformed gas, and the resultant reformed gas is fed to the energy converter FC. In this reformer, the vapor of the reformed fuel formed in the vaporizer 2 is selectively returned back to the reformed fuel tank 6.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system continuing the operation of a fuel cell even when a failure is generated at an operation supplying gas to the fuel cell. SOLUTION: A fuel cell system 10 for circulating hydrogen gas supplied to an anode of the fuel cell has an opening/closing valve 66 in an exhaust gas exhausting passage 64 branched from an anode exhaust gas passage 63. At the system 10, if an abnormality is found in an invertor of the hydrogen pump 65 disposed in the gas passage 63, a hydrogen pump 65 is stopped, and the switching valve 66 performs control to prolong an opening period per unit time length. Since the gas passage 63 communicates with a dilution unit 26 by lower pressure when the valve 66 is opened, hydrogen discharged from a hydrogen tank 23 flows into the dilution unit 26 through a fuel cell 22 and the gas passage 63. Accordingly, the system continues to supply the hydrogen to the fuel cell 22 and can continue power generation even when the pump 65 is stopped. COPYRIGHT: (C)2005,JPO&NCIPI
