A new ultrathin anion exchange membrane (AEM) is proposed for low cost AEM electrolysis. The that thin membranes offer include reduced mass transport resistance and ohmic resistance. membrane electrode assembly (MEA) with a thinner membrane will have improved hydroxide ion due to the shorter ion transfer pathway. We fabricated a MEA with a commercially available A-901 membrane (9 um thick) and non-noble metal catalysts. We determined the efficiency stability of this ultrathin membrane using electrochemical impedance spectroscopy
