Non-Fluorinated Membranes Thickness Effect on the DMFC Performance
Vasco Freitas Silva; Valter B. Silva; R. Reissner; S. Vetter; A. Mendes; L. M. Madeira; S. P. NunesIn order to study the influence of the proton exchange membrane thickness on the direct methanol fuel cell (DMFC) performance, sulfortated poly (ether ether ketone) (sPEEK) membranes with a sulfonation degree (SD) of 42% and thicknesses of 25, 40, and 55 pm were prepared, characterized, and tested in a DMFC. These polymeric membranes were tested in a DMFC at several temperatures by evaluating the current-voltag...
