“…It is due to combined effect of higher operating temperature and the improved threephase reaction zone resulted from hot-pressing. However, the performance of MPh20PWA120 membrane is comparable with that of DBSA-doped PEG/SiO 2 hybrid membrane from our recent study [15] under similar conditions. Although the performance of MEA made from our hybrid membrane is temporarily not comparable with that of Nafion 115 membrane, further improvement of the cell performance is to be anticipated by carefully optimizing the interface when precursor sol-penetrated electrodes are used to fabricate the MEA.…”

“…The authors have mainly focused on structural stability and proton conductivities. In recent publications of our group, preparation, characterization and the feasibility of proton conducting hybrid membranes based on SiO 2 /poly(ethylene glycol) (PEG) containing 4-dodecylbenzene sulfonic acid (DBSA) as electrolyte in PEMFC has been demonstrated [13][14][15].…”

SUMMARYDirect methanol fuel cells have the potential to power future microelectronic and portable electronic devices because of their high energy density. One of the major obstacles that currently prevent the widespread applications of direct methanol fuel cells is the methanol crossover through the polymer-electrolyte membrane. Methanol crossover is closely related to several factors including membrane structure and morphology, membrane thickness, and fuel cell operating conditions such as temperature, pressure, and methanol feed concentration. This work presents a comprehensive overview of the state-ofthe-art technology for the most important factors, affecting methanol crossover in direct methanol fuel cells. In addition, the current and future directions of the research and development activities, aiming to reduce the methanol crossover are reviewed and discussed in order to improve the performance of direct methanol fuel cells.

“…Cross-linking will solve the problem of acid leaching from the membranes under hydrated conditions by effectively immobilizing the acid within the polymer matrix due to formation of the cross-linked networks. The feasibility of proton conducting hybrid membranes based on SiO 2 /poly(ethylene glycol) (PEG) containing 4-dodecylbenzene sulfonic acid (DBSA) as electrolyte in PEMFC has been demonstrated by several researchers [12,16,17].…”
