The perfluorinated ion exchange membrane (PFIEM) was the crucial materials in the proton exchange membrane fuel cell (PEMFC) and chlor-alkali industry, which widely used in the fuel cell, chlor-alkali industry, vanadium battery, etc. As one of the key components, the structure and properties of the PFIEM determine the performance of the battery or cell. Annealing was a kind of traditional technological process, which was simple and convenient, being widely used in the research of the PFIEM performance. In this review, according to different properties of the ionic membrane, we mainly outline the annealing effect of perfluorinated ion exchange membranes on the proton conductivity, methanol permeability, mechanical properties, permselectivity, etc., respectively. The characteristics of the research at present and developing directionare summarized.
