GB/T 46104-2025 Power fluctuation adaptability testing methods of water electrolysis system for hydrogen production

Scope

This document specifies the test conditions, reagents, test preparations, measuring instruments, test items and test indicators, test methods, and test reports for the power fluctuation adaptability test of electrolytic water hydrogen generation systems.
This document is applicable to the power fluctuation adaptability test of alkaline electrolytic water hydrogen generation systems and proton exchange membrane electrolytic water hydrogen generation systems with a hydrogen production capacity of 5 m3/h or more. The power fluctuation adaptability test of anion exchange membrane electrolytic water hydrogen generation systems shall be implemented in accordance with the corresponding standards.
Note: Unless otherwise specified, the standard conditions in this document are a temperature of 0°C and a pressure of 101.325 kPa (absolute pressure). All gas volumes in this document are expressed in terms of their volumes under standard conditions.
