GB/T 45539-2025 Technical requirements of proton exchange membrane eletrolyzer
Basic Information
Scope
This document specifies the naming rules, general requirements, technical requirements, inspection rules, marking, and requirements for factory documentation for proton exchange membrane electrolyzers (hereinafter referred to as "PEM electrolyzers").
This document applies to the design and manufacture of PEM electrolyzers with a rated hydrogen production pressure of less than or equal to 10 MPa and a rated hydrogen production capacity of 1 m3/h to 500 m3/h per electrolyzer. PEM electrolyzers with a rated hydrogen production pressure greater than 10 MPa and PEM electrolyzers with a rated hydrogen production capacity of less than 1 m3/h or greater than 500 m3/h shall refer to this document for implementation.
Note: Unless otherwise specified, all pressures refer to gauge pressure. In this document, standard conditions are defined as a temperature of 0℃ and a pressure of 101.325 kPa (absolute pressure). The volumes of hydrogen and oxygen in this document refer to their volumes under standard conditions.
