Electroceramic support materials can help reducing the noble-metal loading of iridium in the membrane electrodes assembly (MEA) of proton exchange membrane (PEM) electrolyzers. Highly active anodes containing Ir-black catalyst and submicronic Ti₄O₇ are manufactured through screen printing technique. Several vehicle solvents, including ethane-1,2-diol; propane-1,2-diol and cyclohexanol are investigated. Suitable functional anodic layer with iridium loading as low as 0.4 mg cm⁻² is obtained. Surface properties of the deposited layers are investigated by atomic force microscopy (AFM). The most homogeneous coating with the highest electronic conductivity is obtained using cyclohexanol. Tests in PEM electrolyzer operating at 1.7 V and 40 °C demonstrate that the CCM with anode coated with cyclohexanol presents a 1.5-fold higher Ir-mass activity than that of the commercial CCM.

电陶瓷载体材料可以帮助减少质子交换膜（PEM）电解器的膜电极组件（MEA）中铱的贵金属负载。通过丝网印刷技术制造了含有Ir-黑催化剂和亚微米Ti ₄ O _7的高活性阳极。几种媒介溶剂，包括乙烷-1,2-二醇；研究了丙烷1,2-二醇和环己醇。铱含量低至0.4 mg cm ^-2的合适的功能性阳极层获得。沉积层的表面性质通过原子力显微镜（AFM）研究。使用环己醇可获得具有最高电子电导率的最均匀涂层。在运行于1.7 V和40°C的PEM电解槽中进行的测试表明，阳极涂有环己醇的CCM的Ir-质量活性是市售CCM的1.5倍。
