Water management is improved in solid polymer electrolyte fuel cells by employing capillary channels or wicks in the lands that separate the reactant distribution channels in the flow fields. Capillary action moves water within these micro- sized capillary channels or wicks. Appropriate designs can be used to assist in the removal of water from the cell and/or in the redistribution of water from relatively wet regions in the cell to relatively dry regions.
