Abstract. The objective of this work is to demonstrate the potential of the nanoporous silicon and corresponding hybrid materials based on it as proton conductors in general, with a specific focus on its potential applications in fuel cells. Hybrid inorganic/ organic structures were fabricated and analysed in the view of further applications in miniaturized fuel cells technology. Taking into account the advantages obtained by nanotructuration, nanostructured porous silicon was used as matrix for both protonic polymer (Nafion) impregnation and catalyst (Pt) deposition.
