Low-temperature water electrolysis using an anion conductive polymer electrolyte has several potential advantages over other technologies, however, the fabrication of durable alkaline electrodes remains a challenge. Detachment of catalysts results in the loss of electrochemical surface area. Simple mixtures of ionomer and catalyst can suffer from poor catalyst adhesion because only physical adhesion is used to bind the components together. A family of chemically bonded, self-adherent, hydroxide conducting ionomers were synthesized and tested under alkaline electrolysis conditions with nickel ferrite anode electrocatalysts and platinum-nickel cathode catalyst. The ionomers are based on hydroxide conducting poly(norbornene) polymers used as the solid polymer electrolyte in alkaline fuel cells and electrolyzers. The synthesized terpolymer ionomers have been functionalized to provide pendant sites for covalent chemical bonding of bis(phenyl)-A-diglycidyl ether to the ionomer, catalyst, and porous transport layer. The electrodes show excellent adhesion between the catalyst particles, porous transport layer and ionomer, as determined by adhesion measurements and electrolysis performance. The AEM electrolyzer had stable voltage performance under high current density (1 A/cm² at 1.83 V (67% voltage efficiency)) for extended time periods (>600 h) without degradation.

与其他技术相比，使用阴离子导电聚合物电解质的低温水电解具有几个潜在的优势，但是，耐用的碱性电极的制造仍然是一个挑战。催化剂的分离导致电化学表面积的损失。离聚物和催化剂的简单混合物可能会因催化剂粘附性差而受到影响，因为仅使用物理粘附将组分粘合在一起。在碱性电解条件下，使用铁酸镍阳极电催化剂和铂镍阴极催化剂合成并测试了一系列化学键合、自粘附、氢氧化物导电离聚物。离聚物基于在碱性燃料电池和电解槽中用作固体聚合物电解质的氢氧化物导电聚（降冰片烯）聚合物。合成的三元共聚物离聚物已被功能化，为双（苯基）-A-二缩水甘油醚与离聚物、催化剂和多孔传输层的共价化学键合提供悬垂位点。通过粘附测量和电解性能确定，电极在催化剂颗粒、多孔传输层和离聚物之间表现出优异的粘附性。AEM电解槽在高电流密度（1 A/cm²在 1.83 V（67% 电压效率））延长时间段（>600 小时）而不会退化。
