TRANSPORT PHENOMENON IN NEW CLASS OF PROTON EXCHANGE MEMBRANES DESIGNED FOR ELEVATED TEMPERATURE APPLICATIONS

摘要

1. A New accelerated Membrane Durability Test was designed and successfully employed to determine the degradation process of SPES-40 membrane in fuel cell environment. 2. Under Experimental Conditions (30℃_1atm_100%RH), degradation mainly happened in O_2 side Future Work 1. Durability Test of SPES membranes under various conditions (Temperatures, pressures, catalysts) 2. Durability Test on other new PEMs (SPEEK, PSSA etc. ) 3. Use other characterization methods for studying membrane durability.
