Abstract

A CO2 separator for a direct methanol fuel cell (DMFC) includes a single-layered membrane or a multi-layered membrane. In addition, (i) the membrane has a plurality of diffusion channels extending from an inside of the membrane to an outside of the membrane facing the inside, and mean diameters of the diffusion channels on the outside of the membrane are at least three-times greater than mean diameters of the diffusion channels on the inside of the membrane; and (ii) the inside and the outside of the membrane, and inner surfaces of the diffusion channels are hydrophobic.
