摘要： A fuel cell system includes: a fuel cell (100); a secondary cell (200) that receives and stores surplus power by which output of the fuel cell (100) is greater than power demanded of the system if the output is so, and that compensates for shortfall by which the output of the fuel cell (100) is less than the power demanded of the system if the output is so; a voltage measurement portion (600) that measures voltage of the fuel cell (100); a current measurement portion (600) that measures current of the fuel cell (100); and a control portion (700) that performs a control such that the voltage of the fuel cell (100) does not exceed or equal a pre-set high-potential avoidance voltage. If a current-voltage characteristic of the fuel cell (100) declines by at least a pre-determined amount from an early-period level, the control portion (700) re-sets the high -potential avoidance voltage to a value that is smaller than an early-period set value.

摘要： Under the condition that a converter (51) lowers an output voltage of a fuel cell (2) and performs an activation process for a catalyst of the fuel cell (2) and supply of an oxidant gas from a compressor (31) to the fuel cell (2) is stopped, a reduction current is measured by a current sensor (2a) while performing scan to change the output voltage of the fuel cell (2) within a predetermined range by the converter (51) as a measurement of cyclic voltammetry and the measurement value is integrated by a control device (6). According to the integrated value, the control device (6) obtains a charge amount of an electrode catalyst of the fuel cell(2) so as to judge whether the charge amount is smaller than a degradation judgment value and displays the judgment result on a display device (55). Thus, it is possible to accurately judge whether the electrode catalyst of the fuel cell is degraded.

摘要： There is disclosed a fuel cell system or the like capable of sufficiently reducing an exhaust hydrogen concentration even in a case where a fuel cell is operated in a state of a low power generation efficiency. A bypass valve is arranged between an oxidation gas supply path and a cathode-off gas channel. In a state in which supply of an oxidation gas to a cathode falls short, pumping hydrogen is included in a cathode-off gas. Therefore, a valve open degree of the bypass valve is regulated, and a flow rate of bypass air is regulated to control the exhaust hydrogen concentration.
