Abstract[English]
An electrochemical cell cathode catalyst layer includes electrocatalyst particles, an electrocatalyst support having an electronically conductive porous material including a plurality of pores with a diameter of less than or equal to 10 nm having a surface morphology comprising a plurality of peaks and valleys, the surface morphology being configured to contain the electrocatalyst particles within the plurality of pores and to enhance mass transport of molecular oxygen to the electrocatalyst particles by adsorbing molecular oxygen to the surface morphology, and an ionomer adhered to the electrocatalyst, the electrocatalyst support, or both.[French]
Une couche de catalyseur de cathode de cellule électrochimique comprend des particules d'électrocatalyseur, un support d'électrocatalyseur ayant un matériau poreux électroniquement conducteur comprenant une pluralité de pores ayant un diamètre inférieur ou égal à 10 nm ayant une morphologie de surface comprenant une pluralité de pics et de creux, la morphologie de surface étant configurée pour contenir les particules d'électrocatalyseur à l'intérieur de la pluralité de pores et pour améliorer le transport de masse d'oxygène moléculaire vers les particules d'électrocatalyseur par adsorption d'oxygène moléculaire à la morphologie de surface, et un ionomère adhérant à l'électrocatalyseur, au support d'électrocatalyseur, ou aux deux.
