1 Scope

This document describes the basic inspection, basic test and performance test methods of proton exchange membrane electrolyzer (hereinafter referred to as "PEM electrolyzer"). Specifies the requirements for test reports. This document is applicable to PEM electrolyzers with a rated hydrogen production pressure less than or equal to 10MPa and a single cell rated hydrogen production capacity of 1m3/h~500m3/h. PEM electrolyzers with a rated hydrogen production pressure greater than 10MPa, or a rated hydrogen production capacity less than 1m3/h or greater than 500m3/h PEM electrolyzer shall be implemented as a reference. Note. Unless otherwise specified, pressure refers to gauge pressure. The standard state in this document is temperature 0°C and pressure 101.325 kPa (absolute pressure). The volume of oxygen refers to the volume under standard conditions.

3 Terms and definitions

The terms and definitions defined in GB/T 24499 and GB/T 45539 apply to this document.

4 Basic inspection

4.1 Check the PEM electrolyser product manual. 4.2 Use visual method to check whether the appearance and structure of PEM electrolyzer are intact and whether there are any defects such as damage and scratches. 4.3 Use visual method to check whether the PEM electrolyzer label is affixed to the designed position and whether the content of the label is complete and clear. 4.4 The polarity of the PEM electrolyzer should be checked. The wiring terminals and electrical connections should be inspected to confirm whether they meet the requirements. During normal operation test, use a voltmeter to check the polarity of the PEM electrolyzer terminals. 4.5 If there is an inspection line on the PEM electrolyzer, it should be inspected to avoid short circuit, open circuit, etc. 4.6 The gas, water pipeline interfaces and electrical interfaces of the PEM electrolyzer shall comply with the requirements of the instructions and meet the requirements of installation, operation, inspection and maintenance. need. ......
