The overall objective of the project is to develop a nanostructured electrolyte membrane suitable for operating at 150-
in high temperature PEMFCs based on a new composite multifunctional material made by the synergic combination of zeolites, ionic liquids and polymers. This electrolyte membrane will have the following properties:
§ High ionic conductivity: =100 mS/cm at
§ Suitability for operating at temperatures between 130-
(the membrane materials are conceived to be thermically stable up to
. Membrane performance will be validated on single cells at temperatures up to
§ Good chemical, mechanical and thermal stability up to
§ Durable (<1% of performance degradation during the first 1000 hours working).
§ Low fuel cross-over (<five times lower than Nafion; methanol permeability = 3x10-7 cm2 s-1)
§ Reduced fabrication costs compared to current technology (< 400 EUR/m2).
