Abstract：

?Sulfonated polyether ether ketone (SPEEK) proton exchange membranes are generally prepared by first sulfonating polyether ether ketone (PEEK) and then dissolving and casting it, which has problems such as complex preparation process and low conductivity. This research innovatively integrates sulfonation and membrane forming process to achieve efficient preparation of gel proton membrane (GSPEEK) with controllable sulfonation degree in one step. The unique "fish scale" like microstructure of GSPEEK membrane greatly enhances its proton conductivity. At a solid content of 10% and a film-forming temperature of 40 ℃, the conductivity can reach 167.0mS/cm. Its proton conductivity is 4.05 times that of normal SPEEK membrane and 2.45 times that of Nafion 117 commercial membrane, respectively. Assembled into proton exchange membrane electrolysis hydrogen production membrane electrode (MEA) for testing, the results showed that when the voltage was 2.4 V, the current density of GSPEKK-10 membrane was 1000 mA/cm2. Compared with the 600 mA/cm2 and 400 mA/cm2 of normal SPEEK membrane and Nafion-117 membrane, its water electrolysis performance was significantly improved, which has potential industrialization prospects.
