摘要

Polymer-electrolyte-membrane fuel cell has a region of the electrolyte membrane lying next to a feed connection (7) on the cathode side formed as a moistening zone (10) for the cathode gas. Flow deviations (11) for anode gas are arranged on the fluid distribution plate of the anode at least in the region of the moistening zone.
