<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing freezing of an exhaust channel after finish of warm-up. <P>SOLUTION: After finish of warm-up (S20, Yes), focusing temperature T2 of an oxidant gas exhaust flow channel is detected (S30), and, if the focusing temperature T2 is below 5°C, (a first given temperature), an I/C bypass control supplying air from the air compressor without passing it through a cooling unit is carried out (S50). Then, a focusing temperature T2 is detected (S60), and, if it is above 10°C (S70, Yes), the I/C bypass control is finished (S100). Further, if the focusing temperature T2 is not above 10°C (S70, No), a temperature (FC temperature T1) of the fuel cell is detected, and the I/C bypass control is finished (S100) if the FC temperature T1 is above 95°C as an allowable temperature of the fuel cell (S90, Yes). <P>COPYRIGHT: (C)2009,JPO&INPIT |
