PROCEDE DE PREPARATION D'UNE ELECTRODE POREUSE POUR DISPOSITIF ELECTROCHIMIQUE

摘要

The invention relates to a method for preparing a porous electrode including a porous substrate impregnated with particles of a catalytic metal element, including the following steps: a step of impregnating a porous substrate made of vitreous carbon, which is cross-linked with a precursor of said catalytic metal element in a supercritical fluid; and a step of decomposing said precursor of said catalytic metal element, which results in said catalytic metal element remaining.
