Superior AEM water electrolysis

AEM Water Electrolysis

Controlling oxygen vacancies and mass transfer for superior AEM water electrolysis The ultimate goal of developing non-precious-metal electro-catalysts for water electrolysis is the realization of large-scale cost-effective hydrogen production, which requires the use of high current densities (≥500 mA/cm2 at 1.8–2.4 V). In lieu of that, a group of collaborating researchers published a study in the Journal of Applied Catalysis … Read More
