China Hydrogen Energy Expo 2025 Serie-1-AEM electrolyzers
In The 4th Hydrogen Energy & Fuel Cells Expo China (China Hydrogen Energy Expo 2025) which was held on March 26 to 28 in Beijing, AEM electrolyzers become superstar. 10 innovative companies showcased their most advanced AEM electrolyzer products, including one companies debut world first 1MW single system model AEM electrolyzer.
AEM (Anion Exchange Membrame) electrolyzers are often described as a cross between alkaline and PEM electrolysers, with all the benefits of both, but none of their disadvantages.
AEM machines share PEM’s ability to quickly ramp up and down in response to variable wind and solar power, but without the need for the expensive platinum and iridium group catalysts required by PEM, giving it similar costs to alkaline electrolysers, but with greater efficiency. Another advantage of AEM electrolyser is safety, the diluted KOH solution in an AEM electrolyser is much safer to handle than the ALK electrolyser.
I will present the photoes, videos, and the detailed specifications of four AEM electrolyzers (English version) showcased in China Hydrogen Energy Expo 2025, with my comments on the applications.
