Water electrolysis electrode catalysts
Electrolysis, which can produce clean hydrogen without carbon emissions, is attracting attention as one of the key technologies for the hydrogen industry. Heesung Catalysts is developing electrocatalyst technology for water electrolysis with high efficiency and quality. We are developing and supplying electrode catalysts for polymer electrolyte membrane electrolysis. Catalysts containing precious metals (platinum, iridium) and alloy catalysts are mainly in use.
Water damage rescue
Anode catalyst
An IrOx-based catalyst that separates water fed to the anode of a water electrolysis device into oxygen, hydrogen cations (proton), and electrons.
Chemical formula : 2H2O → O2 + 4H+ + 4e–
Cathode catalyst
A precious metal catalyst that recombines hydrogen cations and electrons to produce hydrogen. Generally, catalysts based on precious metals (Pt, Pt alloys, etc.) are used.
Chemical reaction formula : 4H+ + 4e– → 2H2
