| 英文摘要 | electrochemical oxidation of carbon supports for pt/c catalysts can cause degradation of proton exchange membrane fuel cells (pemfcs). to improve the oxidation resistance of the catalyst supports, tungsten carbide (wxcy) was investigated as a substitute for carbon supports in pemfcs. the pt/c and pt/wxcy samples were oxidized using the chronoamperometry method. the electrochemical active area of the two samples was measured using cyclic voltammetry. furthermore, the pt/c and pt/wxcy catalysts were applied to single cells to compare their performance degradation after oxidation. as a result, the single cell prepared with pt/wxcy catalyst showed higher oxidation resistance than the contrastive cell prepared with pt/c catalyst. |
