THE PROJECT TEAM WILL DEVELOP A NON-PFSA-BASED MEMBRANE FOR PEMFCS THAT MEETS PERFORMANCE (0.75 W/CM2 AT 0.7 V) AND DURABILITY (25,000 H) REQUIREMENTS FOR MDVS AND HDVS; DEMONSTRATE SCALABLE ROLL-TO-ROLL MANUFACTURING OF THE MEMBRANE PROTOTYPE; AND PERFORM A TECHNOECONOMIC FEASIBILITY ANALYSIS BASED ON SHORT- STACK AND M2FCT VALIDATION DATA. THIS ENTAILS MAJOR PROGRESS TOWARDS HIGH-VOLUME MANUFACTURING OF PFSA- FREE PEMFCS.
