<P>PROBLEM TO BE SOLVED: To provide a fuel cell separator wherein generated water effectively wets an electrolyte film facing an upstream region of an oxidizing agent flow passage and the water is smoothly discharged in a downstream region of the oxidizing agent flow passage. <P>SOLUTION: In this fuel cell separator having an inlet and an outlet where a flowing fluid is injected and discharged and the flow passage provided on a surface facing a membrane electrode assembly and communicating the inlet and the outlet, the cross section of the flow passage is made smaller step-wisely so that the flow rate of the flowing fluid in a direction of the fluid flowing becomes faster. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
