Reactant flow channel configuration to facilitate water removal

An exemplary fuel cell component comprises a reactant distribution plate including a plurality of channels configured for facilitating gas reactant flow such that the gas reactant may be used in an electrochemical reaction for generating electricity in a fuel cell. Each of the channels has a length that corresponds to a direction of reactant gas flow along the channel.
