In recent times, hydrogen has drawn significant attention as a potential clean energy resource as an alternative to fossil fuels. In particular, there has been active research and development of water electrolysis technology that extracts hydrogen from water to produce green energy and avoids the emission of greenhouse gasses. The proton exchange membrane water electrolyzer (PEMWE) technology, which is currently present in some handful of advanced countries holds core material technology and uses expensive noble metal-based catalysts and perfluorocarbon-based proton exchange membranes. Such technology results in high costs of system…
