Abstract

A humidifier for a fuel cell has a stacked unit of several water-permeable membranes which are parallel to each other and are arranged spaced apart form each other. On the edges of the membranes, a sealant is applied which closes a flow space between neighboring membranes fluid-tightly and serves as a spacer.
