A solid polymer fuel cell that utilizes liquid fuel such as methanol should prevent generated water from residing in a ventilation port close to an anode, to thereby suppress degradation of a MEA. The fuel cell includes an anode, an anode-side collecting electrode, a sealing material located along a perimeter of a solid polymer electrolytic membrane and interleaved between the electrolytic membrane and the anode-side collecting electrode, and a discharging device that discharges a product generated through electric reaction on the anode. The sealing material is provided in a frame-shape around the anode. The discharging device is a ventilation port formed on the sealing material, and a water repellent material is provided at least one of inside the ventilation port and between the ventilation port and the anode.
