“…The interest on Polymer Electrolyte Fuel Cells (PEFC) technology as energy source for portable application has increased due to the characteristics of high energy density, high efficiency and no pollution of these devices [1][2][3]. "Air-breathing" stack is an emerging class of fuel cells for all those low power devices actually served by conventional batteries, because it does not require sub-systems for air supply and humidification.…”

“…For their use in electric cars, or as energy source for portable electrical apparatus (personal computers, cellular telephones, etc. ), the most convenient fuel cells for weight and low working temperature are at present the so‐called polymer electrolyte membrane fuel cells (PEM FC) 1–3. In these cells, electricity is produced by an electrochemical reaction that involves oxidation of the fuel at the anode with the production of protons.…”

We briefly discuss the state of the art of polymer electrolyte membrane fuel cells and suggest that the main obstacles to the commercial development of these fuel cells are essentially the high costs and poor characteristics of present proton conducting membranes. A strategy for the preparation of improved nanocomposite membranes based on the introduction of proton conducting lamell? in the polymeric matrix of present ionomeric membranes is then discussed. Due to their high proton conductivity (in some cases even higher than 10(-1) S cm(-1)), tailor made lamellae obtained by exfoliation of superacid metal (IV) phosphonates are particularly suitable for the preparation of these hybrid membranes. The expected positive influence of the dispersed lamellae on important properties of proton conducting membranes, such as swelling, mechanical resistance, proton transport, and diffusion of methanol, are also discussed. The methods used to obtain good lamellar dispersions into ionomeric polymers and the preparation and main characteristics of some hybrid membranes are also briefly described. The presence of nanoparticles of metal phosphonates in the electrodic interfaces Nafion/Pt already considerably improves the electrochemical characteristics of fuel cells in the temperature range 80-130 degrees C. The increased working temperature of the fuel cell considerably reduces CO poisoning of the platinum electrodes and allows better control of the cooling system, thus overcoming important obstacles to the development of medium temperature PEM fuel cells.
