A method and device for fuel cell heat and water management is provided. A thermally and electrically conductive hydrophilic heat and mass transport element is provided to the fuel cell spanning from inside to outside the cell. The transport element is deposited between current collector and gas diffusion layers, where heat is transported along the transport element from an interior portion of the element inside the cell to an exterior portion of the element outside the cell. Liquid water is transported along the element into or out of the cell, and heat is removed from the exterior portion by any combination of radiation, free convection and forced convection, and where the liquid water is removed from the exterior portion by any combination of convection driven evaporation and advection. The water is added to the cell from the exterior to the interior by any combination of advection and capillary wicking.
