中文摘要	oxygen reduction reaction (orr) attracted extensive interests due to its importance in fuel cells. platinum is well known the best catalyst for the orr; however, several reasons limited the use of pt as the orr catalyst. first of all, pt is expensive due to its limitation in the earth. secondly, pt is easily poisoned by co which exists in reformed gases or by the intermediates from alcohol (crossover from anode for direct alcohol fuel cells) electrooxidation on cathode. therefore, it is necessary to explore non-noble metal electrocatalysts for orr. in this work, we deposited iron phthalocyanine (fepc) on different carbon supports, including vulcan xc72, black pearl, ketjin, and also homemade highly-graphic mesoporous carbon (hgmc) to produce carbon-supported fepc catalysts. the physical properties of the catalysts were characterized by xrd and tem. the activity and stability of these catalysts towards the orr were investigated in alkaline media. the mechanism and kinetics of the orr on the carbon-supported fepc catalysts will be discussed. anion-exchanged membrane fuel cell performances with the carbon-supported fepc as the cathode catalyst will be displayed. the relationship between the surface structure of the carbon-supported fepc catalysts and their activities will be discussed based on both the experimental results and dft simulations.
