Patent

CA 2403517

A membrane electrode assembly (MEA) is provided which comprises an annealed polymer electrolyte membrane (PEM). Additionally, the MEA may include annealed catalyst layers annealed in contact with the annealed PEM. Additionally, methods of manufacture are provided. MEA's according to the present invention may be used in an electrochemical cell, such as a hydrogen fuel cell.

La présente invention concerne un ensemble électrode à membrane qui comprend une membrane d'électrolyte polymérique recuite. Cet ensemble électrode à membrane comprend, de plus, des couches de catalyseur recuites, en contact avec la membrane d'électrolyte polymérique recuite. Par ailleurs, cette invention concerne des techniques de fabrication. On peut utiliser cet ensemble électrode à membrane dans une pile électrochimique telle qu'une pile à hydrogène.
