To provide a gas-liquid separator which satisfactorily separates water in spite of its compact size, without suppressing a flow of cathode off-gas from a fuel cell.SOLUTION: A gas-liquid separator comprises: an introduction part A which receives cathode off-gas; a discharge part B which discharges the cathode off-gas; and a collection part C, located at a boundary between the introduction part A and the discharge part B, which separates and collects water contained in the cathode off-gas. An introduction passage 21a for the cathode off-gas in the introduction part A and a discharge passage 22c for the cathode off-gas in the discharge part B are located in a positional relationship where they are shifted from each other. At a position where the introduction passage 21a and the discharge passage 22c are shifted, there is provided a separation wall W which separates water when the cathode off-gas from the introduction passage 21a makes contact therewith. A water storage space S is provided at a location, in the collection part C, which is below the separation wall W.SELECTED DRAWING: Figure 2 【課題】燃料電池からのカソードオフガスの流れを抑制することなく、小型でありながら良好に水を分離する気液分離器を構成する。【解決手段】カソードオフガスを受け入れる導入部Ａと、カソードオフガスを排出する排出部Ｂと、導入部Ａと排出部Ｂとの境界に配置され、カソードオフガスに含まれる水を分離して回収する回収部Ｃとを備えている。導入部Ａにおけるカソードオフガスの導入流路２１ａと、排出部Ｂにおけるカソードオフガスの排出流路２２ｃとがずれた位置関係に配置され、導入流路２１ａと排出流路２２ｃとのずれた位置に導入流路２１ａからのカソードオフガスが接触して水を分離する分離壁Ｗが配置され、回収部Ｃの分離壁Ｗより下側に貯水空間Ｓが配置されている。【選択図】図２
