AI Technical Summary

Technical Problem

质子膜在进入加热喷涂会因受热失水变形，由于膜电极的制作要求会对质子膜，及喷涂后带有催化层的质子膜进行整平，粘贴等操作，在生产中，这种方式不仅对人员操作的要求严格，细节要求高，而且容易使质子交换膜出现拉扯变形，使得催化层出现微观裂痕、留白且不利于连续生产，同时以这两种方法制得的膜电极一致性也较低；

Benefits of technology

1、本实用新型在CCM制备前，先将两层边框膜与质子膜贴合好后形成密封组件，再在边框膜两侧各复合一层留有有效区域窗口的保护膜后形成质子膜边框膜保护膜三合一质子膜再进行收卷，改善喷涂过程中催化层涂覆错位，解决催化剂浆料溅射污染问题；
