ABSTRACT:
A separator for separating a gas/liquid mixture for a direct methanol fuel cell (DMFC) comprises a closed channel with at least one channel section whose wall completely or partially consists of a hydrophobic, gas-permeable membrane, in which the cross-sectional area of the channel decreases continuously or in steps from an inlet opening to an outlet opening and sections of the channel wall not constituted of the membrane are defined by a one-piece machined body.
