Low-cost anion exchange membrane water electrolyzers are a new technology for the production of hydrogen. Instead of using the traditional noble-metal or transition metal oxide-based catalysts, carbonaceous electrocatalysts are of great interest due to their huge structural and compositional variety and unrestricted abundance. In this study, we report the optimization of membrane electrode assembly performance of anion exchange membrane water electrolyzers through binder synthesis, binder optimization with both platinum group metal and non-platinum group metal oxygen evolution reaction (OER) catalysts. Optimization of electrode showed dependence on binder content, catalyst type, and electrode fabrication method.
