Abstract:
The invention relates to a process for the formation of pores of controlled shape, dimensions and distribution in a polymer matrix comprising a step of embedding silicon nanowires and/or nanotrees in a nonpolymerized polymer matrix or a nonpolymerized polymer matrix in suspension or in solution in at least one solvent, a step of curing the polymer matrix, and a step of removing the silicon nanowires and/or nanotrees by chemical treatment. The process of the invention can be used for the manufacture of a proton exchange membrane fuel cell active layer. The invention has applications in the field of manufacture of proton exchange membrane fuel cells, in particular.
