通过在120 °C下一起加热非晶Nafion膜和催化剂层来制备共结晶催化剂涂覆膜(CCM),以形成用于固体聚合物电解质(SPE)水电解的膜电极组件。共晶化处理有效地增强了膜与催化剂层之间的结合,并增加了催化剂层的疏水性。与传统CCM相比,具有共结晶CCM的SPE水电解槽在80 °C下在2000 mA cm− 2下降低了0.09 V的槽电压,并且提高了稳定性。
A cocrystallized catalyst-coated membrane (CCM) is prepared by together heating amorphous Nafion membrane and catalyst layers at 120 °C to develop the membrane electrode assembly for solid polymer electrolyte (SPE) water electrolysis. The cocrystallization treatment effectively reinforces the bonding between membrane and catalyst layers, and increases the hydrophobicity of the catalyst layers. The SPE water electrolyser with the cocrystallized CCM decreased cell voltage by 0.09 V at 2000 mA cm−2at 80 °C and improved the stability in comparison with the conventional CCM.
