Catalytic material, catalyst slurry, membrane electrode, and fuel cell

The invention relates to a catalytic material, the catalytic material comprises a platinum-carbon catalyst, an ionomer and a high-free-volume polymer, the high-free-volume polymer is a high molecule with the following general molecular formula: # imgabs 0 #, R1 and R2 are independently selected from one of the following groups: # imgabs 1 #. According to the application, the high-free-volume polymer is added into the catalytic material, and the molecular formula of the high-free-volume polymer is as follows: # imgabs 0 #; and the free volume can be used as an oxygen transmission channel, so that the influence of the pore-forming process on the catalytic performance and proton conduction of the fuel cell is avoided. 本申请涉及一种催化材料，所述催化材料包括铂碳催化剂、离聚物、高自由体积聚合物，所述高自由体积聚合物为具有如下分子通式的高分子：#imgabs0#其中，R1、R2各自独立地选自如下基团中的一种：#imgabs1#本申请通过在催化材料中加入高自由体积聚合物，其本身的自由体积即可作为氧传输通道，避免了造孔过程对燃料电池的催化性能和质子传导造成影响。
