摘要： A fuel cell includes a cathode side separator. An oxygen-containing gas flow field is formed on a surface of the cathode side separator. The oxygen-containing gas flow field includes an inlet channel having a plurality of flow grooves connected to the oxygen-containing gas supply passage, an outlet channel having a plurality of flow grooves connected to the oxygen-containing gas discharge passage, and an intermediate channel having flow grooves with both ends connected to the inlet channel and the outlet channel respectively. The flow grooves of the outlet channel are longer than the flow grooves of the inlet channel, and the flow grooves of the outlet channel are narrowed toward the oxygen-containing gas discharge passage.
