Abstract

The methanol crossover is a major problem to operate a direct methanol fuel cell system. The diffusivity of methanol in a water-swollen polymer electrolyte membrane may be influenced by the state of water in the membrane. The methanol diffusivity in sulfonated poly (1,3-dihydro-3-oxoisobenzofuran-1,1-diyl-1,4- phenyleneoxy-1,4-phenylenecarbonyl-1,4-phenylene-oxy-1,4-phenylene) (SC-PEK) was independent on the state of water. It was simply correlated to the total degree of swelling of the polymer.
