Abstract
A porous silicon zone is metallized by performing in situ reduction of metallic ions dissolved in an aqueous solution and fixing of the metallic particles obtained on said zone in a single step. This step consists in particular in bringing the solution containing the metallic ions into contact with the zone to be metallized, the surface whereof has previously been functionalized to enable in situ reduction of the metallic ions and fixing of the metallic particles. Functionalization of the porous silicon zone is achieved by grafting two particular and distinct types of chemical functions. The first function used is a chelating chemical function for the metallic ions and/or for the metal corresponding to the metallic ions, whereas the second function is a reducing chemical function for the metallic ions. Such a metallization can be used for producing an electrically conducting porous diffusion layer of a fuel cell.
