METALLISIERUNG EINER ZONE VON PORÖSEM SILIZIUM DURCH IN SITU REDUZIERUNG UND ANWENDUNG IN EINER BRENNSTOFFZELLE

摘要

Metalizing at least a porous silicon zone comprising terminal hydroxide groups, performed during a step of bringing the porous silicon zone into contact with metallic ions dissolved in an aqueous solution containing at least an organic solvent promoting the step of bringing into contact, is claimed. The porous silicon zone, before the step of bringing into contact, has been grafted by two distinct types of chemical functions, respectively for reducing the metallic ions and for chelating the metallic ions and/or the metal corresponding to the metallic ions. An independent claim is also included for fabricating fuel cell comprising at least forming electrically conducting porous diffusion layer consisting of metalized porous silicon zone formed by metallization of a porous silicon zone comprising terminal hydroxide groups.
