<P>PROBLEM TO BE SOLVED: To provide a fuel cell system that can solve water stagnation in a fuel cell stack without degrading the fuel cell stack. <P>SOLUTION: One end of the fuel cell stack 1 is mounted on a stack support plate 3a via a piezoelectric element device 5, and the other end is mounted on a stack support plate 3b via a slide guide 6. The stack support plates 3a and 3b are fixed to a frame and the like with stack fittings 2. The fuel cell stack 1 is supplied with fuel gas, oxidant gas and cooling water from bellows pipes 4. A control unit 13, if detecting water stagnation in the fuel cell stack 1, outputs a control signal to a piezoelectric element drive circuit 14 to cause the piezoelectric element drive circuit 14 to output a driving signal. The driving signal displaces the piezoelectric element device 5 to oscillate the overall fuel cell stack 1. <P>COPYRIGHT: (C)2004,JPO |
