| 英文摘要 | in this research, the fuel starvation phenomena in a single proton exchange membrane fuel cell (pemfc) are investigated experimentally. the response characteristics of a single cell under the different degrees of fuel starvation are explored. the key parameters (cell voltage, current distribution, cathode and anode potentials, and local interfacial potentials between anode and membrane, etc.) are measured in situ with a specially constructed segmented fuel cell. experimental results show that during the cell reversal process due to the fuel starvation, the current distribution is extremely uneven, the local high interfacial potential is suffered near the anode outlet, hydrogen and water are oxidized simultaneously in the different regions at the anode, and the carbon corrosion is proved to occur at the anode by analyzing the anode exhaust gas. when the fuel starvation becomes severer, the water electrolysis current gets larger, the local interfacial potential turns higher, and the carbon corrosion near the anode outlet gets more significant. the local interfacial potential near the anode outlet increases from ca. 1.8 to 2.6 v when the hydrogen stoichiometry decreases from 0.91 to 0.55. the producing rate of the carbon dioxide also increases from 18 to 20 ml min(-1). crown copyright (c) 2009 published by elsevier b.v. all rights reserved. |
