Claims (1)
- セパレータ本体の表面に流体流路を画成する凹凸が前記セパレータ本体の幅方向に複数連続して形成されてなる凹凸部を有する燃料電池用セパレータであって、
前記セパレータ本体の端部に設けられるシール部と、前記シール部と前記凹凸部のうち前記セパレータ本体の幅方向端部に位置する凸部との間に設けられるセパレータ変形抑制部と、を備え、前記セパレータ変形抑制部と前記セパレータ変形抑制部に隣り合う前記凸部との間に形成される経路の圧力損失は、前記流体流路の圧力損失よりも高く、
前記セパレータ変形抑制部は、前記燃料電池用セパレータを含むセルが積層される積層方向に加わる荷重に対して変形を抑制可能な剛性を有すると共に、前記凸部の長手方向両端部に沿って且つ該長手方向両端部の間の領域に沿って設けられている、燃料電池用セパレータ。
