SANS INVESTIGATION OF A NEW GENERATION OF HYBRID MEMBRANES FOR LONG-LIVED ELECTROLYZERS AND FUEL CELLS.
We recently presented the elaboration of a new generation of hybrid membranes for PEMFC applications endowed with promising performances and durability, A chemically and physically active Sol-Gel (SG) phase was grown within a host membrane. Promising performances and durability were obtained. Combining AFM and SANS experiments we determined the structural features of the SG phase and the sPEEK nanostructure. To combine performance and durability, an in-depth study of the morphology of the membrane versus the chemistry of the SGPs is essential. This information can only be obtained by examining a large number of chemistry and formulation in order to have a predictive approach of the key parameters governing the final properties. We will vary (i) the SGPs chemistry/functionality/formulation and (ii) the SG phase content. This study will allow understanding the parameters controlling the SG localization and morphology. The results are expected to provide a comprehensive understanding of the structure/transport/durability/functional properties interplay, which is of fundamental interest to improve the design of efficient, durable and performing membranes.
