英文摘要 | commercial nafion (r)-115 (trademark registered to dupont) membranes were modified by in situ polymerized phenol formaldehyde resin (pfr) to suppress methanol crossover, and so3- groups were introduced to pfr by post-sulfonatation. a series of membranes with different sulfonated phenol formaldehyde resin (spfr) loadings have been fabricated and investigated. sem-edx characterization shows that the pfr was well dispersed throughout the nafion (r) membrane. the composite membranes have a similar or slightly lower proton conductivity compared with a native nafion (r) membrane, but show a significant reduction in methanol crossover (the methanol permeability of spfr/nafion (r) composite membrane with 2.3 wt.% spfr loading was 1.5 x 10(-6) cm(2) s(-1), compared with the 2.5 x 10(-6) cm(2) s(-1) for the native nafion (r) membrane). in direct methanol fuel cell (dmfc) evaluation, the membrane electrode assembly (mea) using a composite membrane with a 2.3 wt.% spfr loading shows a higher performance than that of a native nafion (r) membrane with 1 m methanol feed, and at higher methanol concentrations (5 m), the composite membrane achieved a 114 mw cm(-2) maximum power density, while the maximum power density of the native nafion (r) was only 78 mw cm(-2).
