Water electrolysis electrode catalysts
Water electrolysis uses electricity to split water into hydrogen and oxygen. When powered by renewable energy, it enables clean hydrogen production with reduced carbon emissions and is considered a key technology for the hydrogen industry. Electrocatalysts for proton exchange membrane water electrolysis (PEMWE) play an important role in improving the efficiency of hydrogen and oxygen evolution reactions, contributing to the performance and stable operation of water electrolysis systems.
Heesung Catalysts develops and supplies electrocatalysts for proton exchange membrane water electrolysis (PEMWE). Based on precious-metal catalysts such as platinum (Pt) and iridium (Ir), as well as alloy catalyst technologies, we provide water electrolysis electrocatalyst solutions with high catalytic activity and durability.
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
