NI-Based porous electrode for water electrolysis and the preparation method thereof

US application US18/986,096 filed - earliest publication US 2025/0236969 A1Water electrolysis technologies are crucial for addressing significant modern challenges, especially in the areas of sustainable energy and environmental protection. During electrolysis, the water molecules are efficiently split into hydrogen and oxygen using electricity. Hydrogen, being a clean and adaptable energy source, holds great promise for reducing greenhouse gas emissions and moving towards a greener future. Hydrogen produced through water electrolysis can be used for various applications, including fuel cells, reducing our reliance on fossil fuels. The economic and environmental sustainability of water electrolysis significantly depends on the development of efficient and costeffective electrocatalysts, particularly at the cathode side.This patent application pertains to the field of water electrolyzers, specifically to electrodes 5 for water electrolysis, and more particularly to the preparation and use of non-noble catalysts for electrodes in water electrolyzers.
