Direct methanol fuel cells electro-osmotic drag

Ren, X., Henderson, W. and Gottesfeld, S. 1997. Electro-osmotic drag of water in ionomeric membranes—New measurements employing a direct methanol fuel cell. Journal of the Electrochemical Society 144 L267-L270. [Pg.174]

Kreuer et al. [25] investigated the membrane properties, including water sorption, transport (proton conductivity, electro-osmotic water drag and water diffusion), microstructure and viscoelasticity of the short-side-chain (SSC) perfluorosulfonic acid ionomers (PFSA, Dow 840 and Dow 1150) with different lEC-values. The data were compared to those for Nafion 117, and the implications for using such ionomers as separator materials in direct methanol and hydrogen fuel cells discussed. Tire major advantages of PFSA membranes were seen to be (i) a high proton conductivity. [Pg.340]
