| description | To provide a fuel cell stack capable of extending service life with an inexpensive configuration.SOLUTION: With a fuel cell stack, at least one separator of a cathode separator and an anode separator in at least one unit cell of a plurality of unit cells includes, in a region adjacent to a cooling liquid manifold of the unit cell in a surface direction, a sacrificial electrolytic corrosion region that is not bonded to an insulation sheet adjacent in a stacking direction and a seal region adjacent to the sacrificial electrolytic corrosion region in the surface direction and bonded to the insulation sheet. In the sacrificial electrolytic corrosion region, a cooling liquid lead-in/out region of the separator is tabular in contact with the insulation sheet. A region other than the cooling liquid lead-in/out region in the sacrificial electrolytic corrosion region has an uneven shape at least partially not in contact with the insulation sheet.SELECTED DRAWING: Figure 1
【課題】安価な構成で寿命を長くすることができる燃料電池スタックを提供する。【解決手段】複数の単セルの内の少なくとも１つの単セルにおいて、カソードセパレータ及びアノードセパレータの内の少なくとも１つのセパレータは、前記単セルの冷却液マニホールドに面方向に隣接する領域に、積層方向に隣接する絶縁シートと接着されていない犠牲電食領域と、当該犠牲電食領域と面方向に隣接し且つ当該絶縁シートと接着されているシール領域を有し、前記犠牲電食領域において、前記セパレータの冷却液導出入領域は、前記絶縁シートと接する平板状であり、当該犠牲電食領域における当該冷却液導出入領域以外の領域は、当該絶縁シートと少なくとも一部接しない凹凸状である、燃料電池スタック。【選択図】図１ |
