InactiveCN103367781BSimple processing methodEfficient processing methodSolid electrolyte fuel cellsRubber materialPolymer science
The invention belongs to the field of polymer electrolyte materials for fuel cells, and particularly relates to a sulphur-modified thermosetting polymer proton exchange membrane and a preparation method thereof. The proton exchange membrane comprises a base body rubber material, a metal unsaturated sulfonate, a vulcanizing activator, a vulcanizing accelerator and sulphur. According to the preparation method, in-situ sulfonation modification and in-situ sulphur modification of rubber are simultaneously completed in a high-temperature hot-pressing process, sulfonic acid groups are effectively grafted on a rubber molecular chain, and a large amount of cyclical sulfides is generated, thus the glass-transition temperature of the rubber is greatly increased, the rubber is transformed into thermosetting plastics, and therefore excellent size stability, heat stability, chemical stability and electrochemical stability are endowed to the proton exchange membrane. The preparation method provided by the invention is simple in process, high in efficiency and low in cost, and is environmental-friendly; the prepared sulphur-modified thermosetting polymer proton exchange membrane has the advantages of high proton conductivity, low methanol permeability, high size stability and the like, and can meet the use requirement of a direct-methanol fuel cell.
