Abstract
(EN)
Disclosed are membrane electrode assemblies having a cathode layer comprising a carbon oxide reduction catalyst that promotes reduction of a carbon oxide; an anode layer comprising a catalyst that promotes oxidation of a water; a polymer electrolyte membrane (PEM) layer disposed between, and in contact with, the cathode layer and the anode layer; and a salt having a concentration of at least about 10 uM in at least a portion of the MEA.
(FR)
L'invention concerne des ensembles électrodes à membrane ayant une couche cathodique comprenant un catalyseur de réduction d'oxyde de carbone qui favorise la réduction de l'oxyde de carbone ; une couche anodique comprenant un catalyseur qui favorise l'oxydation de l'eau ; une couche de membrane électrolytique polymère (PEM) disposée entre, et étant en contact avec, la couche cathodique et la couche anodique ; et un sel ayant une concentration d'au moins environ 10 uM dans au moins une partie du MEA.
