A PEM Water Electrolyzer Stack is the core electrochemical component of a proton exchange membrane water electrolyzer. It uses electricity to split water into hydrogen and oxygen through multiple electrolysis cells. The stack integrates key components such as membranes, electrodes, catalysts, porous transport layers, bipolar plates, and sealing structures. It is characterized by high current density, fast response, compact structure, and good adaptability to fluctuating renewable power. PEM stacks are mainly used in green hydrogen production, industrial hydrogen supply, renewable energy storage, power-to-gas applications, and hydrogen refueling infrastructure.
The upstream industry provides membranes, catalysts, porous transport layers, bipolar plates, sealing materials, and other stack components. The midstream industry performs cell assembly, stacking, sealing, compression, electrical connection, testing, and performance verification to manufacture PEM water electrolyzer stacks. Products are mainly differentiated by power rating, operating pressure, current density, efficiency, and service life. Downstream applications include renewable hydrogen production, industrial hydrogen supply, energy storage, power-to-gas projects, and hydrogen refueling. Market demand is driven by renewable energy development, hydrogen policies, electrolyzer investment, electricity costs, and demand for flexible hydrogen production.
