摘要：
The impedance behaviors of direct methanol fuel cell anode using mesocarbon microbeads supported Pt-Ru catalysts were studied. A loop reflecting an inductive behavior appears at the low-frequency end only when the anode is at higher overpotential. The Nafion content in the catalyst, the MEA hot press condition and the effects of the cell temperature on the impedance behaviors of the anode electrode were also investigated.
