The performances of direct methanol fuel cells (DMFC) are affected by the methanol cross-over, due to the concentration gradient and electrosmosis between the anodes and cathodes. In this study, Polytetrafluoroethylene (PTFE) has been sputter deposited on conventional proton conducting membranes, Na
## Abstract Composite membranes madeβup of sulphonated polyetheretherketone (SPEEK, DSβ=β0.5) and of a sulphonated and silylated hybrid organicβinorganic derivative of polyphenylsulphone (SiSPPSU, DSβ=β2) were prepared and characterised. The water and methanol uptake, as well as thermal properties,
Generally, standard R&D procedures regarding the proton exchange membrane (PEM) development for direct methanol fuel cell (DMFC) applications do not allow direct conclusions concerning the PEM limiting characteristics. In this regard, a recent developed DMFC model is used to predict the influence of
