    • A thickened ion exchange polymer dispersion is obtained by applying ultrasonic vibration or a shearing force to an ion exchange polymer dispersion having a fluorinated polymer having sulfonic acid groups as an ion exchange polymer uniformly dispersed in a dispersion medium so that the viscosity of the dispersion at 25° C. at a shear rate of 10 (1/s) increases 2-2000 times in a thickening step. When formed into a membrane, the dispersion can forms an ion exchange membrane having a uniform and small thickness, high strength, which is free from cracking and shows constant swelling in water and steam. Further, a layer formed by applying a coating solution containing this dispersion and a catalyst powder comprising catalyst metal particles and a carbon support loaded with the catalyst metal particles to a substrate can be used to prepare a membrane-electrode assembly as a catalyst layer for at least one of the cathode and the anode by providing the catalyst layer adjacently to an ion exchange membrane. Because the catalyst layer is highly strong, has few defects and is excellently smooth, a high-performance membrane-electrode assembly for solid polymer electrolyte fuel cells can be obtained.
    • 通过对具有磺酸基的氟化聚合物作为离子交换聚合物均匀分散在分散介质中的离子交换聚合物分散体施加超声波振动或剪切力,使得分散体在25℃下的粘度 在10(1 / s)的剪切速率下,在增稠步骤中增加2-2000次。 当形成膜时,分散体可以形成具有均匀且小的厚度,高强度的离子交换膜,其没有破裂并且在水和蒸汽中显示恒定的溶胀。 此外,可以使用通过将含有该分散体的涂布溶液和包含催化剂金属颗粒的催化剂粉末和负载有催化剂金属颗粒的碳载体的催化剂粉末涂布到基板上而形成的层,以制备作为催化剂层的膜 - 电极组件 通过相对于离子交换膜提供催化剂层,阴极和阳极中的至少一个。 由于催化剂层强度高,缺点少,光滑性好,因此可以得到固体高分子电解质燃料电池用高性能膜 - 电极组件。
