摘要： PROBLEM TO BE SOLVED: To provide a gas diffusion membrane for a solid polyelectrolyte fuel cell which is superior in water management in a wide range of battery reaction ranging from a high electric current density area to a low electric current density area, and which does not obstruct a battery reaction, and in which permeation of the gas is uniform. SOLUTION: In a gas diffusion membrane 10, a recess 13 is installed from the front surface toward the rear face of a hydrophobic porous membrane 12 formed of a hydrophobic binder resin and a conductive material. When this gas diffusion membrane 10 is positioned in the fuel cell so that its rear face will come to the electrode side, a superior water management capability is demonstrated. In other words, in the low electric current density area, the generated water is prevented from coming off since the porous membrane is hydrophobic and therefore the water is retained within the electrolyte membrane, while in the high electric current density area, the large quantity of generated water is evaporated, diffused through holes of the porous membrane, and condensed in the porous membrane, but the generated water is exhausted via the recess as a water passage. In addition, the battery reaction is not obstructed since the rear face contacting the electrode is flat and smooth and has a large contacting area with the electrode. Furthermore, since no penetration hole is installed in the porous membrane, the permeation of the gas also becomes uniformized. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：解决的问题：提供一种固体聚电解质燃料电池用气体扩散膜，其在从高电流密度区域到低电流密度区域的广泛的电池反应范围内，在水管理上优越，以及这不妨碍电池反应，并且其中气体的渗透是均匀的。解决方案：在气体扩散膜10中，从由疏水性粘合剂树脂和导电材料形成的疏水性多孔膜12的前表面向后表面安装凹部13。当该气体扩散膜10位于燃料电池中使得其后表面将进入电极侧时，显示出优异的水管理能力。换句话说，在低电流密度区域中，由于多孔膜是疏水性的并且因此水保持在电解质膜内，因此防止产生的水脱落，而在高电流密度区域中，大量的产生的水蒸发，通过多孔膜的孔扩散，并在多孔膜中冷凝，但是产生的水通过凹槽作为水通道排出。此外，由于与电极接触的后表面平坦且光滑并且与电极的接触面积大，所以电池反应不被阻碍。此外，由于在多孔膜中没有安装贯通孔，气体的渗透也变得均匀。版权所有（C）2006，JPO＆NCIPI
