Water electrolysis is widely regarded as a promising solution for supplying green hydrogen at scale. Electrolyzer devices use electricity to drive the water-splitting reaction, producing streams of H2 and O2 gas from pure water, aqueous solutions, or steam. Among the different electrolyzer technologies, proton exchange membrane (PEM) based devices are more efficient, compact, and inherently safer, making them a popular candidate for industrialization [2]. However, the use of precious metal catalysts in the electrode layers is hindering the deployment of this critical technology to supply the infrastructure needed to meet current and future green hydrogen demands. As a result, many researchers are focused on improving the efficiency and reducing manufacturing costs of PEM-based electrolyzer devices.
