Description
技术领域
本发明涉及质子交换膜燃料电池生产技术领域，具体涉及一种低离子析出热熔型边框膜及其制作方法。
背景技术
燃料电池是一种将存在于燃料与氧化剂中的化学能直接转化为电能的发电装置。燃料电池具有零排放、无振动噪音、负荷响应性好、高可靠度等优点。燃料电池通常可分为碱性燃料电池、磷酸型燃料电池、熔融碳酸碳燃料电池、固态氧化物燃料电池以及质子交换膜燃料电池等；其中，质子交换膜燃料电池能量转化效率高，可以在室温下快速启动，并且无电解水流失，寿命长，近年来发展迅速，越来越受到重视。
质子交换膜燃料电池的核心部件包括燃料电池第一面催化剂层、质子交换膜、第二面催化剂层、上边框、下边框和两面的气体扩散层。燃料电池膜电极制造过程通常包括催化剂的制浆、催化剂层的涂覆、边框的贴合、气体扩散层的涂布、气体扩散层的贴合；质子交换膜对温度和湿度很敏感，容易随环境温度和湿度的改变而变形，而边框除可以提高电极有效面积之外的膜强度来稳定膜电极尺寸外，还可以避免质子膜与极板的直接接触造成机械损伤而影响整个燃料电池使用寿命，故一种有效贴合的燃料电池膜电极边框可以大大提升燃料电池的运行可靠性和寿命。
现有技术中一般留白区域及催化层的周边一定尺寸的两侧是分别直接与上边框和下边框贴合，在边框贴合过程中，上下两层边框中往往有空气的存在，而边框胶带一般是采用不透气的PEN或PI膜作为基膜然后在其单面涂覆热熔胶制成，此种单面胶带产品复合质子膜虽然能起到支撑边框的作用，但普通热熔胶耐温性和耐老化性差，长期在酸水浸泡下容易出现脱开分层问题，从而导致电芯产品损坏，此外市场上在售的边框胶带产品长期在酸液浸泡下大都会析出N、P、S等化学物质以及金属离子Al、Cu、Ni、Cd、Cr、Pb、Fe等，此类的析出物会极大的影响催化剂层铂的活性从而导致膜电极性能劣化，影响整个电堆的使用寿命。
