Abstract:

Hydrogen is an essential element for a net carbon energy system that provides an alternative to difficult sectors for deep decarbonization, including heavy industry and long-haul transport. Electrolytic hydrogen synthesized through renewables is the most sustainable technology. It offers additional flexibility to integrate intermittent renewable energy and also can be used as seasonal energy storage. High current density, high operating pressure, small electrolyzer size, good integrity, and flexibility are all benefits of proton exchange membrane (PEM) water electrolysis technology. It also has good adaptability to the high volatility of wind and PV power. However, one of the main challenges is its high cost. The cost composition and application status of PEM water electrolysis are summarized in this study, and the research progress in critical materials, preparation technology, and component manufacturing are addressed in depth. According to research, novel structure-design preparation strategies and manufacturing technology are expected to improve electrolyzer design and construction, decrease the cost of raw materials and manufacturing for bipolar plates, decrease ohmic polarization by reducing membrane thickness, and increase the activity and utilization of noble-metal catalysts. Finally, the future R&D direction and target of PEM water electrolysis are proposed. With technology innovation in material performance, optimization of component manufacturing, and an increase in electrolyzer plant scale, significantly reducing the cost of PEM water electrolysis equipment and accelerating the large-scale development of PEM hydrogen production.
