Anion Exchange Membrane Water Electrolyzer (Draft for Comments)

This document applies to the design, manufacture, inspection and testing of anion exchange membrane electrolyzers with a rated hydrogen production pressure of 1.0 MPa to 2.0 MPa and a rated hydrogen production capacity of at least 20 m³/h per electrolyzer body; other pressure or capacity specifications may refer to it. It specifies requirements for structure, materials, manufacture and installation, electrolyte, strength, gas tightness, internal crossover, insulation, gas production, power consumption and variable-load operation, and sets out corresponding test methods, inspection rules and nameplate information. Manufacturers must provide safe handling and lifting instructions, design documents, operating manuals and installation and maintenance documentation, covering operation, hazardous-substance handling, protection in explosive atmospheres, ventilation, maintenance inspections and repairs.
