摘要：
In methanol fuel cell applications, the commercial Nafion membrane has not only high cost but also poor proton selectivity. In order to overcome this contradiction, a low-cost sulfonated polyarylethersulfone (SPAES) was used as matrix to prepare a SPAES crosslinked polyvinyl alcohol (PVA) film (SPAES-C-PVA) and SPAES crosslinked sulfonated polyvinyl alcohol (SPVA) film (SPAES-C-SPVA) by heat treatment. The SPAES-C-SPVA film exhibits good mechanical properties, dimensional stability and methanol barrier properties. The proton selectivity of SPAES-C-SPVA is as high as 13.6×104 S•s•cm-3, which is about 3 times and 4.3 times than that of the SPAES and Nafion 117 membrane, respectively. © 2020, Editorial Board of Polymer Materials Science & Engineering.
