将部分结晶的Nafion膜与催化层一起结晶，制备了一种用于固体聚合物电解质水电解的新型催化剂涂层膜。通过破坏性浸泡试验、扫描电子显微镜、压汞试验和单细胞试验对部分共晶CCM的性能和性能进行了评价和分析。结果表明，制备部分晶化Nafion膜和PCCCM的最佳热处理温度和时间分别为100℃4h和120℃4h。PCCCM不仅具有更强的膜与催化层之间的粘附性，而且具有比普通CCM更高的孔隙率。在80℃大气压下，采用新型CCM的固相微萃取水电解槽在2000mA/cm−下的电解电压低至1.748 nV。此外，在2 0 0 0 mA/cm−2下进行了约180h的稳定性试验，电解电压没有明显升高。
A novel catalyst-coated membrane (CCM) for solid polymer electrolyte water electrolysis was fabricated by together crystallizing partial-crystallized Nafion membrane and catalyst layers. The properties and performance of the partial-cocrystallized CCM (PCCCM) were evaluated and analyzed by destructive soaking test, scanning electron microscope, mercury intrusion and single cell test. The results revealed that the optimum annealing temperature and time for fabricating partial-crystallized Nafion membrane and PCCCM was 100 °C for 4 h and 120 °C for 4 h, respectively. The PCCCM not only possessed much stronger cohesion between membrane and catalyst layers, but also had higher porosity than conventional CCM. The electrolysis voltage of the SPE water electrolyser with the new CCM was as low as 1.748 V at 2000 mA cm−2under 80 °C and atmospheric pressure. Moreover, there was no obvious increase of electrolysis voltage during stability test conducted under 2000 mA cm−2for about 180 h.
