Research progress of key materials for hydrogen production from electrolytic water in fluctuating renewable energy environments

The development of renewable energy technologies is critical to achieving carbon neutrality. Green hydrogen, as a secondary non-polluting energy source, is emerging as a major strategy and vehicle for energy development change. In this paper, through the analysis of the characteristics of various types of electrolytic water technologies, the relevant research and problems of PEMWE key component materials are highlighted, and the influence on the existence of PEMWE key materials under renewable energy loads is further discussed. In future research, it is necessary to pay attention to the main reasons of fluctuating renewable energy sources on the decay of material performance in PEMWE devices, as well as to develop new materials to enhance the adaptability and durability to fluctuating loads.
