The limitation of catalyst layer for proton exchange membrane fuel cell (PEMFC) in cost, durability and performance constitutes the bottleneck for the commercialization of fuel cell vehicles. Electrospun catalyst layer, with high catalyst utilization, increased triple phase boundary (TPB) and triple phase channel (TPC), has been developed by many researchers. This paper reviews the research progress in the electrospun catalyst layer for PEMFC, combined with the author’s work. Firstly, the development progress of catalyst layer is summarized, and the catalyst layer is classified and analyzed based on its fabrication method and structure character. Next, the fabrication process, physical property characterization, electrochemical performance analysis and durability characterization of the electrospun nanofiber catalyst layer are described. Finally, further develoment tendency in catalyst layer for PEMFC is viewed by comparion of three kinds of catalyst layers from the viewpoints of TPB, TPC and mass production. Future research topics are discussed
