| 英文摘要 | Nanofiber electrodes fabricated by using the electrospinning technique in the cathode of proton exchange membrane fuel cells gave a peak power density of 0.692Wcm(-2) with an ultralow Pt loading of 0.087mgcm(-2). As the cathode, the electrospun (E_spun) electrodes exposed a high Pt surface to oxygen, with a highly uniform distribution of Pt catalyst and Nafion ionomer, which improved the utilization of Pt. The ionic resistance of the E_spun electrode was decreased owing to the nanofiber structure. The high porosity of the E_spun electrode enhanced the Knudsen diffusion in small pores, which mitigated the oxygen-transfer resistance. The addition of 5wt% polytetrafluoroethylene (PTFE) to the E_spun electrode optimized water management, especially at high current densities. The accelerated stability test showed that the long-term durability of the E_spun electrode is much better than the conventional decal electrode due to the interaction of the carbon support and hydrophilic poly(acrylic acid). |
