Patent

CA 2659469

An electrocatalyst, suitable for use in a fuel cell and especially useful in the anode of a direct methanol fuel cell, is disclosed. The electrocatalyst comprises an alloy having a single crystalline phase, wherein the alloy consists of 5-95at% palladium, 5-95at% ruthenium and less than 10at% of other metals, provided that the alloy does not consist of 50at% palladium and 50at% ruthenium.

La présente invention concerne un électrocatalyseur pouvant être utilisé dans une pile à combustible et se révélant particulièrement utile dans l'anode d'une pile à méthanol direct. L'électrocatalyseur de cette invention comprend un alliage à une seule phase cristalline, lequel alliage se compose de 5 à 95 % atomique de palladium, de 5 à 95 % atomique de ruthénium et de moins de 10 % atomique d'autres métaux, pour autant que l'alliage ne comprenne pas 50 % atomique de palladium et 50 % atomique de ruthénium.
