Role of Ionomers in Anion Exchange Membrane Water Electrolysis: Is Aemion the Answer for Nickel-Based Anodes?
Abstract
The anode oxygen evolution reaction (OER) in anion exchange membrane water electrolysis (AEMWE) limits the process’ overall hydrogen production efficiency. Studies show that nickel-iron (NiFe)-based catalysts show excellent activity toward the OER. In anode catalyst layers, electrocatalysts must be paired with anion exchange ionomers (AEI) to bind the catalyst and conduct hydroxide ions. This work covers the first investigation of the …
