Title: Multi-Hybrid Power Vehicles with Cost Effective and Durable Polymer Electrolyte

Anima Bose, the principal investigator of the project, originally proposed to develop composite membranes to operate PEMFCs at much higher temperatures than 80{degrees}C and to alleviate the flooding problems often encountered in Nafion menmbrane containing fuel cells. The PI has successfully created composite membranes by blending small quantities of octasilane-poss (OSP) with Nafion. The composite membranes exhibited temperature tolerance up to 110{degrees}C without scarifying cell performance as determined by polarization curves and proton conductivity measurements. These membranes also exhibited superior water management performance as evident from the lack of flooding. Furthermore, these fuel cells performed well under reduced humidities. Structural and thermal analyses revealed that these Nafion-octasilane composite membranes are homogenous at concentrations up to 3 wt% of the OSP and that the siloxane offers additional thermal stability.
