Analysis and Characterization of Mechanical Durability of Perfluorosulfonic Acid Proton Exchange Membrane
摘要
Abstract
The mechanical durability of perfluorosulfonic acid proton exchange membrane(PFSA-PEM)plays an important role in the performance,life and service reliability of proton exchange membrane fuel cell(PEMFC).The mechanical durability of homogeneous and enhanced PFSA-PEM was carried out by dry-wet cycle method,and the attenuation mechanism and influencing factors were analyze.The mechanism of enhanced material on mechanical properties,dimensional change rate and durability of PFSA-PEM was verified.The results show that the method can effectively characterize the tensile strength and elastic modulus of PFSA-PEM and give the spatial location information of the local failure point from the thermal imaging,thus,provide a strong basis for further optimizing the manufacturing process parameters and improving the mechanical durability of PFSA-PEM.关键词
