DETAILED DESCRIPTION - The polymer electrolyte membrane fuel cell (102) water management device using electroosmtic pumps for redistributing and removing liquid water, comprises a hydrophilic water transport element (104) spanning from inside the fuel cell to outside the fuel cell and disposed between a gas diffusion layer and a current collector layer in the cell, and an electroosmotic pump. The transport element comprises an intermediate wick outside the fuel cell that is hydraulically coupled to the transport element, and a transport element structure integrated with a flow field structure within the fuel cell. The pump is located outside the fuel cell. The pump is hydraulically coupled to the intermediate wick to actively remove excess water from the flow field structure and the gas diffusion layer through the transport element. The water removal is decoupled from oxidant delivery. The ectroosmotic pump comprises a secondary porous structure layer, a porous pumping element, two electrodes and a housing. The secondary porous structure layer and the intermediate wick are hydraulically coupled. The housing holds the secondary porous structure, the porous pumping element, and the electrodes about the intermediate wick. The water is rejected from the cell. The secondary porous structure layer is an electrical insulator between the pump and the fuel cell, and a particle filter to the pump. The electroosmotic pump further comprises an electric potential across the porous pumping element. The electric potential is sufficient to induce a columbic force on a mobile ion layer on the porous pumping element. A viscous interaction between the mobile ions and the water generates a bulk flow. The electric potential across the porous pumping element is a time varying potential by reducing parasitic loads to the fuel cell. The electric potential is activated when flooding or dry-out is detected or imminent by reducing parasitic loads to the fuel cell. The fuel cell is a fuel cell stack comprising two fuel cells. The fuel cell stack comprises a wicking bus disposed between the pump and multiple layers of the transport element. The bus is operated on by the pump. The bus is a dielectric wick disposed outside the fuel cell. The dielectric wick saturates with water. The dielectric wick hydraulically connects the transport elements with the pump and insulates an electric field of the cell from an electrical field of the pump. The transport element is an electrically conductive wick. The electrically conductive wick is made from a material of carbon cloth, carbon paper, aluminum foam, stainless steel foam and nickel foam. The transport element is a porous hydrophilic water transport layer disposed between a bipolar plate and a gas diffusion layer in the fuel cell. The water transport layer is hydraulically connected to the external electroosmotic pump. The transport element is a porous hydrophilic water transport layer comprising a pattern of cut-outs and/or a pattern of hydrophobic regions arranged in a pattern. The transport layer is hydraulically continuous. The transport layer is disposed between a gas diffusion layer and a current collector layer in the fuel cell. The transport layer is hydraulically connected to the external electroosmotic pump. The electroosmotic pump is disposed to humidify a membrane electrode assembly when using dry gases and low humidity gases in the flow fields. The electroosmotic pump is disposed to humidify hydrogen in an anode current collector on the fuel cell. The electroosmotic pump actively distributes water in the cell between a cathode region and an anode region of the fuel cell.
