<P>PROBLEM TO BE SOLVED: To realize improvement of fuel consumption by suppressing discharge amount of a gas which is worth of utilization as a fuel. <P>SOLUTION: A plurality (a first circulation passage 6 and a second circulation passage 7) of circulation passages to circulate the fuel discharge gas to be discharged from a fuel cell 1 are installed, and a hydrogen separation device 12 provided with a hydrogen transmission membrane 15 in the second circulation passage 7. Then, a purge line 17 provided with a purge valve 16 by being coupled with the hydrogen separation device 12 is installed. By this way, the circulation passages are made to have two systems, and because unnecessary gas is made to be efficiently discharged and a hydrogen gas as a fuel is not discharged at the least, it is possible to realize the improvement of the fuel consumption. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
