<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of raising the temperature of an exhaust valve in simple structure and suppressing freezing in the exhaust valve. <P>SOLUTION: The fuel cell system 1 is equipped with a circulation line 10 circulating and supplying hydrogen offgas exhausted from a fuel cell 2 to the fuel cell 2; an exhaust and drain valve 48 exhausting fluid flowing through the circulation line 10 to the outside; and a coolant passage 51 through which a coolant is circulated and supplied to the fuel cell 2. The exhaust and drain valve 48 has a valve body 61 equipped with a passage 61e communicating the inside of the circulation line 10 with the outside, and the coolant passage 51 is passed through the valve body 61 so as to become independent of the passage 61e. <P>COPYRIGHT: (C)2009,JPO&INPIT |
