Scope

Scope: This standard specifies the terms and definitions, classification and naming, technical requirements, testing and inspection, marking, packaging, etc. of proton exchange membrane (PEM) hydrogen electrolysis systems. This standard applies to PEM hydrogen electrolysis systems with a pressure not less than 0.3 MPa and not more than 5 MPa, and a hydrogen output of not more than 10 Nm3/h under standard conditions per electrolyzer; Main technical contents: The scope of application of this standard is PEM hydrogen electrolysis systems with a pressure not less than 0.3 MPa and not more than 5 MPa, and a hydrogen output of not more than 10 Nm3/h under standard conditions. It specifies the terms and definitions, classification and naming, technical requirements, testing and inspection, marking, packaging, etc. of PEM hydrogen electrolysis systems. The technical requirements of this group standard are formulated as follows: small-scale proton exchange membrane hydrogen electrolysis systems, standalone equipment, hydrogen pipelines, valves and accessories, water pipelines and their accessories, electrical equipment and wiring, automatic control and monitoring, assembly. According to the standard-making work plan and referring to relevant domestic materials, the verification of testing methods was carried out, providing a basis for determining the testing methods. The testing methods involved in this standard are all directly referenced from corresponding national standards and industry standards. The inspection of small-scale proton exchange membrane hydrogen electrolysis systems includes performance testing and safety testing. Among them, hydrogen flow rate, hydrogen dew point, oxygen content in hydrogen, working pressure, and leakage quantity testing belong to performance testing, which requires manufacturers to provide inspection reports and conduct commissioned inspections regularly. Dielectric strength, contact current, and insulation resistance are safety tests, ma
