✦ Synopsis

The performance of solid-polymer-electrolyte DMFCs is substantially influenced by the morphology of the gas diffusion layer (GDL) in the catalytic electrodes. Cells utilizing GDLs made with high-surface-area Ketjen Black carbon, with optimized thickness, show better performance compared with cells utilizing Vulcan XC-72 carbon or 'acetylene black' carbon in the GDL. Cells with a hydrophilic diffusion layer on the anodes and a hydrophobic diffusion layer on the cathodes yield better performance.
