Etude, conception et réalisation d'une pile à combustible miniature pour applications portables

Abstract : This work deals with the realization of a complete miniature fuel cell (PEMFC type) for portable applications (cell phones, PDA). The use of silicon for fuel cell manufacturing enables to use silicon technologies and an easy integration with other electronic devices. The cell membrane is made of microporous silicon treated to ensure the proton conduction. Two solutions are proposed : impregnation with a Nafion®- type ionomer and molecules grafting on the porous silicon surface. Each of those two solutions have been assembled as fuel cells and have reached similar performances (18 mW/cm²). A great work on characterization have been made on the structure of porous silicon (SEM, conductivity measurements, permeability, spectroscopy,...) and membrane treatments (SEM, SIMS).
