The development of proton conducting polymer membranes for fuel cells using sulfonated carbon nanofibres

Abstract

This study describes a new strategy to improve the performance of PEMFCs by the addition of S/CNF. The presence of 2.08 vol.-% S/CNF increased the proton conductivity of a S/EPDM by one order of magnitude, which made it comparable to that of Nation® 117, and without creating an electronic path. Furthermore, the filled membranes showed improved thermal stability and mechanical properties. © 2008 WILEY-VCH Verlag GmbH & Co. KGaA.
