Abstract

Des cathodes inertes permettant la réduction d'oxygène, recouvertes d'une fine couche superficielle à action catalytique, conviennent à des piles à combustible. En présence de méthanol comme combustible, ce revêtement doit en outre présenter des propriétés sélectives que l'utilisation de matériaux en amas semi-conducteurs issus de chalcogénure de métal de transition, toutefois sous forme de poudre ou de fine couche, ne suffit pas à obtenir. La cathode inerte mise au point selon l'invention permet de parvenir aux propriétés catalytiques et sélectives voulues. Son revêtement superficiel mince comprend des amas du type susmentionné, répartis de manière homogène, comme une dispersion colloïdale, et sa production n'implique qu'une quantité minimale de matériau de l'ordre du nanogramme, pour un degré de couverture particulièrement faible avec un coefficient d'efficacité hautement sélectif et catalytique. Le revêtement s'obtient par immersion dans un colloïde qui contient le mélange en amas conjointement avec un stabilisant dans un solvant. Après application du colloïde, le solvant et le stabilisant sont éliminés par traitements thermiques.
