Abstract[English]
An electrochemical cell porous transport electrode (PTE) may include a first region having a first porosity having a surface portion, a second region having a second porosity less than the first porosity and being partially bounded by a shoulder region offset the surface portion in a thickness direction of the PTE, and an anode catalyst layer adhered to the PTE.[French]
Une électrode de transport poreuse (PTE) de cellule électrochimique peut comprendre une première région présentant une première porosité ayant une partie de surface, une seconde région présentant une seconde porosité inférieure à la première porosité et étant partiellement délimitée par une région d'épaulement décalée de la partie de surface dans le sens de l'épaisseur de la PTE, et une couche de catalyseur d'anode collée à la PTE.
