# China export standards for Water electrolyzer (green hydrogen, AEM/PEM)

          Water electrolyzers split water into hydrogen and oxygen using electrical energy, and are a core component of green hydrogen production chains. Exporting alkaline, proton-exchange membrane (PEM), or anion-exchange membrane (AEM) electrolyzers from China involves intersecting regulatory domains: pressure vessel codes govern the electrolyzer stack and gas handling system, electrical safety standards apply to power electronics, and dedicated hydrogen equipment directives or standards—such as ISO 22734 and EN 60335-2-102 in Europe—cover hydrogen production, compression, and dispensing safety. Subsidy schemes and domestic content rules in the EU and US further complicate market access. The pages below compare the applicable pressure, electrical, and hydrogen-specific certification requirements for each market covered.
