<P>PROBLEM TO BE SOLVED: To provide a technology for adjusting efficiently dry and humid state of a reaction gas to be supplied to a fuel cell. <P>SOLUTION: The fuel cell system 1000 is provided with a first and a second dehumidifying parts 330, 340 in an air supply part 300 and supplies a dehumidified reaction gas to a fuel cell 100. To be concrete, a high pressure air outputted by an air compressor 310 is conducted alternately to the first and the second dehumidifying parts 330, 340 by a first switching valve 320. The first and the second dehumidifying parts 330, 340 have a water absorbing member and dehumidifies the high pressure air conducted by the water absorbing member. A control part 400 carries out a recovery treatment respectively to the first and the second dehumidifying parts 330, 340 for recovering dehumidification capacity by utilizing exhausted heat of the fuel cell 100, when the high pressure air is not conducted to these. <P>COPYRIGHT: (C)2010,JPO&INPIT |
