| 英文摘要 | focused on the optimization of the gas diffusion electrode (gde) in an alkaline anion exchange membrane fuel cell (aaemfc), ptfe content and catalyst loading in the catalyst layer (cl) were found to have a substantial effect on the cell performance and electrochemical kinetics. the i-v curves, open circuit voltage, cell resistance, in-situ electrochemical impedance spectroscopy and kinetics analysis have been used to evaluate the electrochemical properties of the fabricated gdes. the results reveal that the optimum ptfe content in the cl of aaemfc is 20%. pt loading ranged from 0.2-1.0 mg/cm(2) was also investigated as a vital parameter for three-phase boundary, cl conductivity and catalyst utilization. ultimately, the highest peak power density of 213 mw/cm(2) was achieved at 50 degrees c from the prepared gde with pt loading of 1.0 mg/cm(2) on pt/c and 20% ptfe in cl of aaemfc. considering the pt-based catalyst effective utilization and cost, however, the platinum requirement can be diminished to close to 0.5 mg/cm(2) in clwithout significant performance loss.
