| 英文摘要 | catalyst-coated membrane (ccm) and catalyzed diffusion medium (cdm) prepared either by brush painting method or by spraying method were compared for direct methanol fuel cell (dmfc) anode and cathode. the pore structure and the morphology of the electrodes were characterized by mercury intrusion porosimetry (mip) and scanning electron microscopy (sem). internal resistance corrected polarization curves were employed to separate the contribution of each compartment of the membrane electrode assembly (mea) to the overall polarization. it was shown that the increased mass transport resistance in the anode diffusion layer made the anode in cdm form act as the methanol barrier. the ccm configuration and the increased pores in micron scales in the catalyst layer were in favor of improving the performance of both anode and cathode. accounting for the effect of methanol permeation, the combination of the anode in cdm form prepared by brush painting method and the cathode in ccm form prepared by spraying method was finally selected as the optimized configuration for mea, which had the highest dmfc performance under near-ambient conditions.
