摘要： The invention relates to a method for depositing a metal M1 onto a carbon layer, as well as to a method for manufacturing an electrode for fuel cells and to a method for manufacturing a fuel cell. The method for depositing a metal M1 onto a porous carbon layer according to the invention includes a step of depositing said metal M1 by means of the electrochemical reduction of an electrolytic solution of a salt of the metal M1, and, prior to said step of depositing the metal M1 by means of electrochemical reduction, a step of depositing a metal M2 by means of chemical reduction using a reducing gas of a salt of the metal M2, the thermodynamic equilibrium potential between the ionic form of the salt of M2 and M2, Eeqionic form of the salt of M2/M2 being greater than the thermodynamic equilibrium potential between the ionic form of the salt of M1 and M1, Eeqionic form of the salt of M1/M1. The invention can be used, in particular, in the field of fuel cells.
