<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of absorbing deformation of a composition member of the fuel cell and giving a desirable surface pressure to an electrolyte membrane. <P>SOLUTION: The fuel cell is provided with a membrane electrode assembly 73 in which electrode catalyst layers 75a, 75c are formed on both sides of an electrolyte membrane 74, a separator SP which pinches the membrane electrode assembly 73, and a gas passage member 78 installed at least at one between the separator SP and the membrane electrode assembly 73. The gas passage member 78 is constructed by laminating a plurality of passage composition members. The plurality of passage composition members include at least two concavo-convex passage composition members 78w having respectively concavo-convex shape, and at least one flat-shape passage composition member 78p is interposed between at least two concavo-convex passage composition members 78w respectively so that the thickness in lamination direction of the whole gas passage member 78 may not change due to mutual position shifting. <P>COPYRIGHT: (C)2009,JPO&INPIT |
