Recent Approaches to Achieve High Temperature Operation of Nafion Membranes

A proton exchange membrane fuel cell (PEMFC), as an efficient energy conversion device, has many advantages, such high efficiency and environmentally friendly zero emissions, is expected to have great potential for addressing the uneven distribution of global green energy. As a core component, performance (PEM) directly affects overall output system. At present, Nafion membranes with good, comprehensive properties are most widely used commercial materials. However, demonstrate inadaptability increase in operating temperatures, rapid decay conductivity. Therefore, enhancing under temperatures low relative humidity (RH) become urgent problem. Although efforts been made solve this problem, it difficult find balance point between high-temperature conductivity stability researchers. In paper, we summarize recent approaches improving temperature from following two perspectives: (1) using different materials modification membranes, (2) applying methods membranes. Based on structural functional characteristics Nafion, non-destructive targeted filling fillers synergy two-phase region vital research directions preparation high-performance composite
