GB/T 45541-2025 Testing method for proton exchange membrane electrolyzer performance

Scope

This document describes the basic inspection, fundamental testing, and performance testing methods of proton exchange membrane electrolyzers (hereinafter referred to as "PEM electrolyzers"), and stipulates the requirements for test reports. This document is applicable to the inspection and testing 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. PEM electrolyzers with a rated hydrogen production pressure greater than 10 MPa and those with a rated hydrogen production capacity of less than 1 m3/h or greater than 500 m3/h shall be implemented as a reference. Note: Unless otherwise specified, all pressures refer to gauge pressures. In this document, the standard state is a temperature of 0 °C 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.
