Abstract

La présente invention concerne un procédé de préparation d'électrodes pour piles à combustible Selon la présente invention une électrode est préparée par formation d'une première suspension aqueuse de catalyseur, addition d'un agent tensio-actif cationique à la suspension, formation d'une deuxième suspension aqueuse de particules de polymère hydrophobe colloïdales, combinaison des deux suspensions et réalisation de l'électrode par applicage du mélange de particules de catalyseur et de polymere à un substrat conducteur suivi du frittage de la couche catalyseur/polymère réalisé. Par le procédé de l'invention une meilleure distribution du catalyseur à travers la structure de l'électrode est obtenue et par suite une électrode ayant une meilleure performance peut être réalisée.
