Fuel Cell Electrolyzer Competitiveness Business Areas

The Future of
Sustainable Energy,
Electrolyzer

Water electrolysis primarily uses electricity from renewable energy sources
(e.g., solar, wind) to produce 'green hydrogen,' which has become an essential
element for carbon neutrality and an important solution for clean energy.

Electrolyzer

  • Electrolyzer
    Water electrolysis is the process of decomposing water (H₂O) into hydrogen (H₂) and oxygen (O₂) using electrical energy. This process occurs in electrolysis cells when electrodes are submerged in water and current flows.

    Our third-generation Solid Oxide Electrolyzer Cell (SOEC) innovates hydrogen production efficiency with over 20% lower electricity consumption than conventional systems.
    Operating in high-temperature environments (700-850℃), it overcomes thermodynamic energy losses and maximizes energy conversion efficiency through a proprietary design that utilizes the fuel cell reverse process.
    It is an industry-customized solution that improves overall system efficiency by over 40%, mainly when linked with industrial surplus heat energy, such as waste heat from nuclear power plants and high-temperature exhaust gas from steel plants.
