| 英文摘要 | A novel PEMFC electrode (E-U electrode) with ultralow platinum is prepared by electrospinning and underpotential deposition techniques. The platinum skin (Ptskin) is in situ deposited on the surface of Pd nanoparticle in the electrospun Pd/ C catalyst layer. The energy-dispersive X-ray spectroscopy (EDS) mapping of the cross-section of a single fiber confirms that the distribution of Pd/C@ Pt-skin catalysts and Nafion1 ionomer matches well in the E-U electrode. The high porosity and large electrochemical surface area (ECSA) of the E-U electrode mitigates the oxygen transfer resistance. The peak power density of the E-U electrode arrives at 0.62 W cm(-2) with a Pt loading of 19 mg cm(-2), which is higher than that of the conventional electrode (0.55 W cm(-2)) with a Pt loading of 100 mg cm(-2). The degradation rate of peak power density of the E-U electrode is only 4.8% after accelerated stability test (AST) for 30000 cyclic voltammetry (CV) cycles, demonstrating a better durability than that of the conventional electrode. The enhanced durability of the E-U electrode is attributed to nanofiber structure and interaction between Pd and Pt in the Pd/C@ Pt-skin catalyst. (C) 2017 Published by Elsevier Ltd. |
