PROBLEM TO BE SOLVED: To provide a separator for polymer electrolytic fuel cell which has a good nature of circulation and diffusion of fuel gas and oxygen-containing gas, particularly prevents moisture contained in circulating gas-liquid mixture from biased flow, clogging of flow passage or the like, by improving cross-sectional shape of the gas passage, gives a high draining performance and stable voltage-current by uniformly supplying gas on a catalyst layer and improving temperature uniformity on the reaction surface, and enables to raise power generating efficiency of the fuel cell and to facilitate manufacturing as well. SOLUTION: The gas passage 12 formed on the separator 1 for the polymer electrolytic fuel cell is shaped in such a cross section as V-shaped, arc-shaped, etc., expanding toward the opening side. |
