Preparation and characterization of the PVDF-based composite membrane for direct methanol fuel cells

PREPARATION AND CHARACTERIZATION OF THE PVDF-BASED COMPOSITE MEMBRANE FOR DIRECT METHANOL FUEL CELLS

Abstract
The polyvinylidene fluoride-sulfonated polystyrene composite membrane with proton exchange
performance, denoted as PVDF-SPS, was prepared using a thermally induced polymerization technique.
The thermal stability of the PVDF-SPS composite membrane was investigated using thermogravimetric
