Electrochemical water splitting has long been considered an effective energy conversion technology for converting intermittent renewable electricity into hydrogen fuel. Proton exchange membrane water electrolysis (PEMWE) is considered one of the most efficient and practical methods for green hydrogen, with the advantages of zero carbon emissions, compact structure, small footprint, high current density, and high purity of hydrogen production. The research is divided into the development of non-noble metal catalysts and the design and additive manufacturing of porous components. While current activities are focused on PEMWE, future work will expand to include alkaline and solid oxide electrolysis as well.
