(FR) COUCHES DE CATALYSEUR ET ÉLECTROLYSEURS
Abstract:
(EN) A catalyst layer for an electrochemical device comprises a catalytically active element and an ion conducting polymer. The ion conducting polymer comprises positively charged cyclic amine groups. The ion conducting polymer comprises at least one of an imidazolium, a pyridinium, a pyrazolium, a pyrrolidinium, a pyrrolium, a pyrimidium, a piperidinium, an indolium, a triazinium, and polymers thereof. The catalytically active element comprises at least one of V, Cr, Mn, Fe, Co, Ni, Cu, Sn, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, Hf, Ta, W, Re, Ir, Pt, Au, Hg, Al, Si, In, Tl, Pb, Bi, Sb, Te, U, Sm, Tb, La, Ce and Nd. In an electrolyzer comprising the present catalyst layer, the feed to the electrolyzer comprises at least one of CO2 and H2O
(FR) L'invention concerne une couche de catalyseur pour un dispositif électrochimique, qui comprend un élément catalytiquement actif et un polymère conducteur d'ions. Le polymère conducteur d'ions comprend des groupes amines cycliques chargés positivement. Le polymère conducteur d'ions comprend au moins un des éléments suivants : un imidazolium, un pyridinium, un pyrazolium, un pyrrolidinium, un pyrrolium, un pyrimidium, un pipéridinium, un indolium, un triazinium et des polymères de ces derniers. L'élément catalytiquement actif comprend au moins un des éléments suivants : V, Cr, Mn, Fe, Co, Ni, Cu, Sn, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, Hf, Ta, W, Re, Ir, Pt, Au, Hg, Al, Si, In, Tl, Pb, Bi, Sb, Te, U, Sm, Tb, La, Ce et Nd. Dans un électrolyseur comprenant la présente couche de catalyseur, l'alimentation vers l'électrolyseur comprend au moins un élément parmi CO2 et H2O.
