Flow field plate, fuel cell stack with a flow field plate and fuel cell system

摘要

The invention relates to a flow field plate (1) for distributing a reactant to an electrode or a gas diffusion layer of a fuel cell, with a flow field core (4) which has at least one channel (6). The flow field core (4) is at least partially formed from a hydrophilic and / or hygroscopic material such that the liquid of a fluid flowing in the at least one channel (6) can be temporarily stored in the flow field core (4). The invention also relates to a fuel cell with a flow field plate and a fuel cell system.
