To provide a fuel cell that can efficiently discharge produced water generated by electrode reaction to the outside.SOLUTION: A fuel cell includes a discharge mechanism F that discharges produced water (H2O) generated at a cathode electrode as a result of electrode reaction in an MEA 40 to an outside. The discharge mechanism F includes a discharge channel 28 through which air, the oxidant, flows, a passageway 29 that connects an oxidant supply channel 21 and the discharge channel 28 so as to be communicated, and allows the produced water generated at the cathode electrode to move into the discharge channel 28, and a discharge unit 20c that discharges the produced water that has moved to the discharge channel 28 to the outside.SELECTED DRAWING: Figure 9 【課題】電極反応に伴って発生した生成水を効率よく外部に排出することができる燃料電池を提供すること。【解決手段】燃料電池は、ＭＥＡ４０における電極反応に伴ってカソード電極にて発生する生成水（Ｈ２Ｏ）を外部に排出する排出機構Ｆを備える。排出機構Ｆは、酸化剤である空気が流れる排出路２８と、酸化剤供給流路２１と排出路２８とを連通可能に接続し、カソード電極にて発生した生成水を排出路２８に移動させる通路２９と、排出路２８に移動した生成水を外部に排出する排出部２０ｃとを備える。【選択図】図９
