摘要
为实现可持续发展,人类对清洁能源的需求不断增加。在众多新型能量存储与转化装置中,质子交换膜燃料电池因具有可将化学能高效、安全地直接转化为电能、应用场景广泛等优点备受关注,而质子交换膜是其核心部件,质子电导率以及机械强度相互制约等问题成为困扰其发展的主要难题。虽然关于质子交换膜单一性能的提高研究已经取得了重要的阶段性成果,但是其关键技术性能相互制约的问题仍困扰其发展,并影响燃料电池的进一步商业化。发展柔性质子交换膜是解决此技术难题的主要策略。基于此,从柔性聚合物材料、结构优化、柔性添加体设计三个方面综述了近年来国内外关于柔性质子交换膜的研究进展,期待为突破柔性质子交换膜的性能瓶颈提供启发。
At present,the demand for clean energy is constantly increasing to achieve sustainable development of human society.Among numerous new energy storage and conversion devices,proton exchange membrane fuel cells(PEMFCs)can directly convert chemical energy into electrical energy.Therefore,PEMFCs have been considered to have the merits of high efficiency,safety and wide application,etc.The proton exchange membrane is the core component of PEMFCs.However,the trade-off of proton conductivity and mechanical strength has become the primary challenge to hinder the development of proton exchange membranes.Although significant progress has been made in improving the single performance,the mutual constraints of key technical properties restrict the development of proton exchange membranes.Most importantly,the road to the commercialization of fuel cells is thus tortuous.We believe that the development of flexible proton exchange membranes is a main strategy to solve this technical challenge.Based on this,this article summarizes the recent research progress on flexible proton exchange membranes,including flexible polymer materials,structural optimization,and flexible additive design,expecting to provide inspiration for breaking through the performance bottleneck of flexible proton exchange membranes.
