Technology Introduction:
This research develops electrocatalytic seawater hydrogen production using high-entropy catalysts and membrane electrolysis for efficient, stable hydrogen energy. Materials prepared via PLMS and hydrothermal synthesis achieve low onset voltages and stability of 1500 hours (100 mA/cm²) and 1000 hours (1 A/cm²). The technology, spanning catalyst development to electrolyzer assembly, enables practical hydrogen production.
Industry Applicability:
This study advances seawater hydrogen production using high-entropy catalyst anodes grown on nickel substrates via pulse laser scanning, achieving low voltage and high durability for industrial use. Optimized cathodes boost electrolysis efficiency, enabling scalable electrolyzer assembly. Extended to membrane and alkaline electrolyzers, enhanced designs improve hydrogen output and purity. It also explores wastewater purification alongside hydrogen production, supporting green energy.
