Overview
"Direct methanol fuel cells (DMFCs), employing liquid methanol as a fuel, offer an attractive option in portable devices due to their simplicity in the system structure (easy storage and supply), no need for fuel reforming or humidification. For obtaining a higher power density, the membranes that show high proton conductivity, and at the same time, low methanol permeability are strongly desired. However, there is achieved only a little progress because of trade-off relations between these parameters. Also the membrane stability, particular to hydrolytic and chemical stability is recognized as a key factor that affects fuel cell performances." This book is the first time that such long-term operation of DMFC was reported since PVA-PAMPS composite are all hydrocarbon membranes made simply of aliphatic skeletons. They are very different from the perfluorosulfonic membranes such as Nafion, or other reported membranes with aromatic skeletons. Therefore this affords the PVA-PAMPS composites unique structure compared to most of the proposed membranes, which suggests the good candidacy of PVA-PAMPS composites when they are intended for use in low temperature DMFCs.Book Details
