摘要
随着燃料电池技术的高速发展，提升燃料电池的性能和寿命，降低整个系统的成本成为制约其推广应用的瓶颈问题。质子交换膜作为质子交换膜燃料电池的核心元件，对整个系统的运行起着至关重要的作用。聚苯并咪唑质子交换膜可用于高温燃料电池系统，增强电池对杂质的耐受度，简化水热管理，进而降低电池的使用成本，是一种理想的Nafion替代材料。但传统的聚苯并咪唑质子交换膜负载磷酸后机械强度下降，在电池运行过程中磷酸易流失，导致电池性能的衰减。本文综述了近些年来不同研究者从不同角度制备的聚苯并咪唑质子交换膜，归纳可以借鉴的策略，为后续的研究提供参考。
Abstract
With the rapid development of fuel cells
the balance between the improvement of performance and lifetime
and the reduction of the cost of the whole system become a bottleneck problem which restricts its application. As the key component of fuel cell
proton exchange membrane ensures the operation of the whole system. Polybenzimidazole (PBI) based high temperature proton exchange membrane (PEM) can greatly enhance the impurity tolerance of fuel cell and simplify its hydrothermal management
which reduce the cost. Therefore
it is an ideal Nafion alternative material. However
traditional PBI based PEM is easy to loss phosphoric acid during the operation and after acid loading
the mechanical strength decreases
resulting in the attenuation of battery performance. Aiming at the problems of PBI based proton exchange membrane
this paper reviews different methods that researchers attempted from various angles
hoping to summarize the general strategies that can be used for reference in the follow-up research.
