The Nafion membrane was modified using chemical deposited Pd in an effort to reduce methanol crossover in DMFC. The surface morphology, crystal structure and chemical composition of the Pd-deposited membranes were characterized. The glass transition temperature (Tg), proton conductivity and methanol-inhibiting performance of the I'd deposited membranes were studied and compared with those of non-modified membranes. It was shown that Pd-modified membrane exhibited better performance in methanol inhibition and proton conductivity than the Nafion (R) 112 membrane.
