    • 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.
    • 使用甲醇等液体燃料的固体高分子型燃料电池,能够防止生成的水滞留在靠近阳极的通气口内,抑制MEA的劣化。 燃料电池包括阳极,阳极侧收集电极,沿着固体聚合物电解质膜的周边定位并且在电解质膜和阳极侧集电电极之间交错的密封材料,以及排出产生的产品的放电装置 通过阳极上的电反应。 密封材料围绕阳极设置成框状。 排出装置是形成在密封材料上的通气口,并且在通气口的内部和通气口与阳极之间的至少一方设置防水材料。
