To provide a fuel cell separator capable of improving fuel cell power generation performance.SOLUTION: A separator 20 is provided in such a manner that the separator comes into contact with a power generation section 11. The separator 20 includes a plurality of projections 31, a gas passage 32, and guide grooves 35, 36. The plurality of projections 31 extend in parallel to each other at intervals and come into contact with the power generation section 11. The gas passage 32 forms a concave groove extending along the projections 31 between the two projections 31 adjacent to each other. Reaction gas flows through the gas passage 32. The guide grooves 35, 36 are formed on surfaces of each projection 31 on a side of the power generation section 11, form grooves extending in the arrangement direction of the projections 31, and extend from portions that come into contact with the power generation section 11 to the bottom of the gas passage 32.SELECTED DRAWING: Figure 7 【課題】燃料電池の発電性能を向上させることのできる燃料電池用セパレータを提供する。【解決手段】セパレータ２０は、発電部１１に当接する態様で設けられる。セパレータ２０は、複数の突条３１と、ガス流路３２と、ガイド溝３５，３６とを有する。複数の突条３１は、互いに間隔を置いて並列して延在するとともに発電部１１に当接する。ガス流路３２は、互いに隣り合う２つの突条３１の間において突条３１に沿って延在する凹溝状をなす。ガス流路３２は反応ガスが流れる。ガイド溝３５，３６は、突条３１における発電部１１の側の面に形成され、且つ、突条３１の並び方向に延びる溝状をなし、且つ、発電部１１に当接する部分からガス流路３２の底部まで延びる。【選択図】図７
