<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of restraining a tendency of becoming large. <P>SOLUTION: On the fuel cell system 1, whole surroundings of a fuel cell stack 10 is covered with a stack case 60, and a running speed of gas exhausted from the fuel cell stack 10 is reduced at the inside of the stack case 60. When the running speed is reduced, moisture with high density contained in the exhaust gas is accumulated at a lower part of the stack case 60, and that with low density is accumulated at an upper part. The gas accumulated at the upper part of the stack case 60 flows into a circulation piping 31 through a gas exhaust port 61, and the gas accumulated at the lower part of the stack case 60 flows into a water draining piping 51 through a water exhaust port 62. <P>COPYRIGHT: (C)2007,JPO&INPIT |
