<P>PROBLEM TO BE SOLVED: To suppress the partial decrease in conductivity between the surface of a press separator in a power generation region and other members and equalize the conductivity. <P>SOLUTION: When a plurality of fluid channels 35 containing parts having different curvatures from each other are arranged in parallel, in at least one surface of the press separator 20, the width in at least any one fluid channel 35 is made wider in a part having a larger curvature out of the parts having different curvatures. The parts where the curvatures of the fluid channel 35 are different include a straight channel 35s in a straight part S and a curved channel 35t in a turn part T of the fluid channel 35, for example. Preferably, the one surface is the surface on a membrane-electrode assembly side. <P>COPYRIGHT: (C)2008,JPO&INPIT |
