摘要

目前，喷涂技术在大规模生产用于质子交换膜水电解（PEMWE）的阳极催化剂层方面引起了人们的兴趣。喷雾油墨中的溶剂是催化剂在油墨中的分散、催化剂层的微观结构和PEMWE性能的关键因素。本文研究了各种纯有机溶剂作为油墨溶剂的传统异丙醇-去离子水（IPA-DIW）混合物的替代品。在表现出比非极性溶剂更好的IrO2分散性的极性溶剂中，2-丁醇（2-BuOH）被选为合适的候选者。PEMWE单电池是使用2-BuOH在不同离聚物含量、喷嘴类型下制造的

Comparative Study on the Organic Solvent of IrO2–Ionomer Inks used for Spray Coating of Anode for Proton Exchange Membrane Water Electrolysis

Currently, spray coating has attracted interest in the mass production of anode catalyst layers for proton exchange membrane water electrolysis (PEMWE). The solvent in the spray ink is a critical factor for the catalyst dispersion in ink, the microstructure of the catalyst layer, and the PEMWE performance. Herein, various pure organic solvents were examined as a substitute for conventional isopropanol-deionized water (IPA-DIW) mixture for ink solvent. Among the polar solvents that exhibited better IrO 2 dispersion over nonpolar solvents, 2-butanol (2-BuOH) was selected as a suitable candidate. The PEMWE single cells were fabricated using 2-BuOH at various ionomer contents, spray nozzle types
