<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of reducing manufacturing cost and narrowing an occupying space by reducing the number of outside pipes for drain. <P>SOLUTION: A unit cell 10 is constituted by arranging a separator on both sides of a membrane electrode assembly having an anode and a cathode on both sides of an electrolyte membrane. A plurality of unit cells 10 are stacked and the both sides of the stack are fixed with end plates 90A, 90B. A gas exhaust hole 4 is continuously formed over the plurality of unit cells 10 and the end plate 90A, and drain holes 8A, 8B are also continuously formed. The ends of the drain holes 8A, 8B are connected to the gas exhaust hole 4 on the end plate 90B side. <P>COPYRIGHT: (C)2007,JPO&INPIT |
