<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of easily carrying out mounting of piping on the fuel cell stack while preventing reduction of sealing characteristics. <P>SOLUTION: Regarding a laminating direction of a power generating cell 11, a communication part 68 of a piping flow passage for fuel gas circulation and a communication flow passage 58 for fuel gas circulation are positioned more outside than the communication part 61 of the piping flow passage 31 for fuel gas supply and the communication flow passage 51 for fuel gas supply, and the communication part 64 of the piping flow passage 34 for oxidizer gas exhaust and the communication flow passage 54 for oxidizer gas exhaust. Regarding the direction of axial lines 61a, 64a of the communication parts 61, 64, face sealing members 71, 74 carry out sealing of the communication parts 61, 64 in a state of being pinched between a moduled piping member 41 and an end plate 14-1, and regarding the direction orthogonal to the direction of the axial line 68a of the communication part 68, a shaft sealing member 78 carries out sealing of the communication part 68 in a state of being pinched between the moduled piping member 41 and a pump 24. <P>COPYRIGHT: (C)2010,JPO&INPIT |
