Abstract
A flow-field plate is provided for distributing a reactant to an electrode or a gas diffusion layer of a fuel cell, the flow-field plate having a gas inlet, and having a plurality of channels defining a flow field. A pressure gradient is present between the gas inlet and the flow field given a state of throughflow, which leads to an intake of exhaust gas flowing in the channels in the direction of the gas inlet. Furthermore, there is a water/gas separator which is fluidically connected to the gas inlet for separating liquid water and/or water vapor from a gas which is connected to the flow field in order to supply the gas separated in the water/gas separator to the flow field. A flow cross-section at the gas inlet or at the gas inlet region is smaller than the flow cross-section at or in the region of the water/gas separator.
