| description | PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of improving the efficiency of power generation and the durability more than a prior art, in restoring the degradation of performance of catalyst due to adhesion of impurities. SOLUTION: In the fuel cell stack 200, two or more unit cells 10 are laminated between a pair of collectors 30, 31, and supply mechanisms 60A, 61A, 62A capable of supplying the unit cells 10 with heat transfer media are extended in a stack direction 500 of the unit cells. Pairs of intermediate collectors 32a, 32b, 33a, 33b are also laminated between the collectors 30, 31 in the stack direction 500, and the pairs of intermediate collectors 32a, 32b, 33a, 33b are inserted between the unit cells 10. Also, the pairs of intermediate collectors 32a, 32b, 33a, 33b sandwich insulators 34, 35 in a stack direction. COPYRIGHT: (C)2011,JPO&INPIT |
