The Effects of Operating Conditions on the Performance of Air-breathing Direct Methanol Fuel Cells

摘要

In this study, we have showed characteristic features of the DMFC single cells under various conditions. The cell performance was affected by some parameters, such as methanol concentration, catalyst loading, membrane thickness, and feeding method. The cells behaved differently depending on the reactant-feeding method and the passive-feed conditions produced the best results among the feeding-conditions tested, regardless of the methanol concentrations.
