PROBLEM TO BE SOLVED: To prevent entry of separated water into an off-gas exhaust port in a gas liquid separator.SOLUTION: A gas liquid separator comprises: a gas liquid separator forming part formed in an end plate of a fuel cell, and composing a part of the gas liquid separator by opening in an end face of thereof; and a cover member composing a part of the gas liquid separator by covering the opening in the gas liquid separator forming part. The gas liquid separator forming part has: a first internal wall part functioning as an off-gas passage and forming a part of a storage part in which water is stored, the first internal wall part having an exhaust port for off-gas, connected to the opening, and formed in a recessed shape in the direction of end plate thickness; and a surrounding part projecting from the first internal wall part along a first direction toward a cover member from the liquid gas separator forming member and surrounding the exhaust port, the end face of the surrounding part in the first direction being offset in a direction opposite to a first direction, from the end face of the entire gas liquid separator forming part in the first direction.SELECTED DRAWING: Figure 5

    【課題】気液分離器におけるオフガスの排出口への分離された水の浸入を抑制する。【解決手段】気液分離器は、燃料電池のエンドプレートに形成されて端面に開口して気液分離器の一部を構成する気液分離器形成部と、気液分離器形成部の開口を覆って気液分離器の一部を構成するカバー部材と、を備え、気液分離器形成部は、オフガスの流路として機能すると共に水が溜まる貯留部の一部を形成し、オフガスの排出口が形成され開口に接続してエンドプレートの厚さ方向に凹状に形成されている第1の内壁部と、気液分離器形成部材からカバー部材に向かう第1の方向に沿って第1の内壁部から突出して排出口を囲む囲み部と、を有し、囲み部における第1の方向の端面は、気液分離器形成部全体における第1の方向の端面から第1の方向とは反対方向にオフセットされている。【選択図】図5
