摘要


本實驗主要目的在於探討添加微孔層(micro-porous layer, MPL)對直接甲醇燃料電池(direct methanol fuel cell, DMFC)的影響。實驗主要分為兩部分:一.改變陰極微孔層碳粉負載量,二.改變陽極微孔層的位置與Nafion含量比。測量在不同條件下的極化曲線(polarization curve)和開路電位(open circuit voltage, OCV)。 實驗結果顯示,陰極微孔層會增加陰極進料質傳阻抗,造成性能下降,但是適量的微孔層碳粉負載量卻會提高開路電位。陽極微孔層也會增加陽極進料質傳阻抗,降低性能。陽極沒有添加微孔層時開路電位最高。

並列摘要


The purpose of this study is to evaluate the effect of micro-porous layer (MPL) on cell performance in direct methanol fuel cells (DMFC). There have tow parts of this study:one is to change carbon loading of MPL in cathode;the other is to change position and Nafion loading of MPL in anode. And then getting the polarization curves and open circuit voltage(OCV). The MPL in cathode decreases mass transport and performance, but suitable carbon loading of MPL will increase OCV. The MPL in anode also decreases mass transport and performance. Anode without MPL has better OCV.
