Abstract[English]
An electrochemical cell includes an anode, a cathode, and a membrane physically separating the anode from the cathode, the cathode having a cathode catalyst layer including an ionomer and an electrocatalyst support substrate forming an ionomer-support interface having a covalent bond between the substrate and the ionomer via a grafting compound, the substrate further having a plurality of terminated hydrophilic groups.[French]
Une cellule électrochimique comprend une anode, une cathode et une membrane séparant physiquement l'anode de la cathode, la cathode ayant une couche de catalyseur de cathode comprenant un ionomère et un substrat de support d'électrocatalyseur formant une interface de support ionomère ayant une liaison covalente entre le substrat et l'ionomère par l'intermédiaire d'un composé de greffage, le substrat ayant en outre une pluralité de groupes hydrophiles terminés.
