PURPOSE:To smoothly let fluid flow even if one portion of grooves is clogged by forming recessed and projecting parts so that a large number of projections are formed zigzag in a fluid flow direction in contact parts on both sides except for the periphery of a separator with electrodes. CONSTITUTION:Air supply passages 1 and fuel supply passages 2 are alternately perforated on one side of the periphery of a separator, and air exhaust passage 3 and fuel exhaust passages 4 are perforated on the other side of the periphery in the same way. Recessed and projecting parts 5 are formed on both sides of the central part except for the periphery of the separator. Each projecting part 5a of the recessed and projecting parts 5 is formed discontinuously and zigzag from fluid supply side to fluid exhaust side. Grooves formed with recessed parts 5b are crooked from the supply side to the exhaust side. |
