On March 28, 2025, China's State Administration for Market Regulation and the Standardization Administration introduced 216 new recommended national standards, including standards for proton exchange membrane (PEM) electrolyzers. These standards, such as GB/T 45539-2025 and GB/T 45541-2025, focus on specifying technical requirements and testing methods for the performance of PEM electrolyzers. The goal of these additions is to bolster the advancement and standardization of hydrogen production technologies, aligning with China's national energy objectives. The approval of these standards signifies that PEM electrolyzer manufacturers must adhere to these criteria to facilitate their products' import and sale within China. Ensuring compliance with national standards is vital for companies seeking to enter the Chinese market with PEM electrolyzer technologies. For companies eager to understand the implications of these new Chinese national standards on their operations, resources like the News Section can provide regular updates. Additionally, businesses can reach out to MPR China Certification GmbH for detailed information and consultations. The announcement emphasizes the importance of staying informed about evolving regulations and certification requirements in China's energy and technology sectors.
