Dimensionally stable multication-crosslinked poly(arylene piperidinium) membranes for water electrolysis

Abstract

Dimensionally stable crosslinked poly(arylene piperidinium)-based AEMs were fabricated and used for alkaline water electrolysis. A high current density of 880 mA cm −2 at 2.2 V in 1 M KOH was achieved by using non-PMG catalysts.
