The present invention relates to a catalyst ink for producing membrane- electrode assemblies for polymer electrolyte fuel cells which comprises, in addition to the typical components - catalyst material, acidic ionomer, and solvent - an additive component comprising at least one low molecular mass organic compound containing at least two basic nitrogen atoms. The invention further relates to processes for producing such catalyst inks and also to their use for producing membrane-electrode assemblies for polymer electrolyte fuel cells.
La présente invention concerne une encre catalytique destinée à la fabrication d~unités membrane-électrodes pour piles à combustible à électrolyte polymérique contenant, en plus des composants courants, à savoir un catalyseur, un ionomère acide et un solvant, un composant supplémentaire constitué d~au moins un composé organique de faible masse moléculaire comprenant au moins deux atomes d~azote basiques. L~invention concerne également un procédé de fabrication de telles encres catalytiques, ainsi que leur utilisation pour la fabrication d~unités membrane-électrodes pour piles à combustible à électrolyte polymérique.
