Abstract
A membrane electrode assembly for an electrochemical cell, in particular a co-electrolysis cell for COreduction reaction, can overcome the problem of parasitic COpumping from cathode to anode side and, at the same time, maintain good Faradaic efficiency towards COreduction reaction in a co-electrolysis system where pure or diluted gaseous COis used. The assembly includes an MEA, having an anode, a cathode, a polymer ion exchange membrane between cathode and anode, an additional ion exchange polymer film between the cathode and the polymer ion exchange membrane and a discontinuous interface formed between the additional polymer film located at the cathode side and the ion exchange membrane.
