Effect of polydimethylsilicone membrane thickness on the rate of methanol evaporation in a passive vapor-feed direct methanol fuel cell

Abstract

In a passive vapor-feed direct methanol fuel cell (DMFC), methanol vapor is typically obtained using a pervaporation plate in a process by which liquid methanol contained in the fuel reservoir undergoes a phase change to vapor in the anodic vapor chamber. This work focuses on Polydimethylsilicone (PDMS) membrane, which is one of the preferred pervaporation plates in this field of study, to investigate the effect of its thickness on the rate of methanol evaporation. A three-dimensional (3D) model was developed by varying the membrane thickness using COMSOL Multiphysics. The rate of methanol evaporation was measured using the Darcy's law equation. The rate of methanol evaporation was found to be inversely proportional to the membrane thickness and the decrease in thickness inevitably lowers the resistance along the membrane and consequently increases the methanol transport through the membrane. This shows that the membrane thickness has a significant influence on the rate of methanol evaporation, and thereby plays an important role in improving the performance of the DMFC.
