New PEM Electrolyte for High Temperature Fuel Cells

50059-98-I New PEM Electrolyte for High Temperature Fuel Cells--Cape Cod Research, Inc., 19 Research Road, East Falmouth, MA 02536-4440; (508) 540-4400 Mr. R. Scott Morris, Principal Investigator Ms. Katherine D. Finnegan, Business Official DOE Grant No. DE-FG02-98ER82544 Amount: $75,000 Proton exchange membrane (PEM) fuel cells appear to be a good candidate for future portable power and transportation applications. Direct oxidation of reformed hydrocarbon fuels in the PEM fuel cell is the next step in the process of utilizing these energy sources in a wide array of operations. To accomplish this objective, new PEMs that can operate at high temperatures need to be developed. The objective of this project is to develop a novel proton exchange membrane (PEM) suitable for use in PEM fuel cells at temperatures in excess of 200¿C. The proposed effort entails computer design and characterization of likely candidate polymers followed by synthesis and characterization of the better choices. Characterization will include electrochemical, thermal and mechanical analysis of the better synthesized polymers to determine if the proposed approach is feasible. Commercial Applications and Other Benefits as described by the awardee: Fuel cells offer a pollution-free alternative to the internal combustion engine and will play a key role in future electric automotive transportation._
