Description:
本发明公开了一种质子交换膜燃料电池用碳纸及其制备方法,制备方法为:以碳纤维配伍一定量气相生长碳纤维、铜粉为主要原料,水溶性聚乙烯醇纤维为增强纤维,先经高速搅拌机搅拌,然后改用低速搅拌设备并添加分散剂将上述原料均匀分散于水中,采用斜网造纸机或侧流式圆网造纸机湿法造纸工艺抄造成基纸,再经酚醛树脂浸渍、热压及碳化、石墨化处理制成质子交换膜燃料电池用碳纸。本发明制备的质子交换膜燃料电池用碳纸具有优异的导电导热性能,良好的强度和较高的透气透湿性能。 The invention discloses carbon paper for a proton exchange membrane fuel cell and a preparation method of the carbon paper, and the preparation method comprises the following steps: mixing carbon fibers with a certain amount of vapor-phase growth carbon fibers and copper powder as main raw materials and water-soluble polyvinyl alcohol fibers as reinforced fibers, stirring by a high-speed stirrer, and uniformly stirring; then low-speed stirring equipment is used, a dispersing agent is added, the raw materials are evenly dispersed in water, base paper is manufactured through the wet-process papermaking technology of an inclined wire papermaking machine or a side-flow type rotary screen papermaking machine, and then the carbon paper for the proton exchange membrane fuel cell is prepared through
