<P>PROBLEM TO BE SOLVED: To solve the problem that it is hard to quickly and simply remove the remaining gas with high energy efficiency after a fuel cell is used in a FC-EV. <P>SOLUTION: A pipe 103 is connected to the FC stack 100 through two electromagnetic valves 111, 112. A pressure sensor is connected to the pipe 103 between the electromagnetic valve 112 and a pipe 102 to measure the reduced pressure 150, and a vacuum tank 130 and its pressure sensor 122 are connected to the pipe 103 between the two electromagnetic valves 111, 112. Namely, the vacuum tank 130 is connected to the pipe 102 through the electromagnetic valve 112 and and connected with the FC stack 100 through the electromagnetic valve 111. The pipe 103 connecting the electromagnetic valve 111 and the FC stack 100 is also connected to a pipe 104 communicating with the regular exhaust system and to a pressure sensor 121 to check the gas pressure between the FC stack 100 and the electromagnetic valve 111. <P>COPYRIGHT: (C)2004,JPO |
