Uniformity, Performance, and Durability of Roll-to-Roll-Coated Iridium Oxide Electrolyzer Catalyst Layers

Published by National Renewable Energy Laboratory | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-11-20T21:02:54Z
Data for "Uniformity, Performance, and Durability of Roll-to-Roll-Coated Iridium Oxide Electrolyzer Catalyst Layers.” This work investigates the use of roll-to-roll coating methods for the production of iridium oxide catalyst layers for proton exchange membrane water electrolyzers. Catalyst layers were produced using two coating methods: slot die and gravure. The film microstructure and uniformity were investigated by electron microscopy. Membrane electrode assembly testing investigated the impacts of coating method and catalyst layer uniformity on electrolyzer performance and durability.
