    摘要： 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.

    摘要： A simple, inexpensive and highly efficient fuel cell has boundary structures made of a photo-sensitive material in combination with selective patterning. Printed circuit board (PCB) fabrication techniques combine boundary structures with two and three dimensional electrical flow path. Photo-sensitive material and PCB fabrication techniques are alternately or combined utilized for making micro-channel structures or micro stitch structures for substantially reducing dead zones of the diffusion layer while keeping fluid flow resistance to a minimum. The fuel cell assembly is free of mechanical clamping elements. Adhesives that may be conductively contaminated and/or fiber-reinforced provide mechanical and eventual electrical connections, and sealing within the assembly. Mechanically supporting backing layers are pre-fabricated with a natural bend defined in combination with the backing layers' elasticity to eliminate massive support plates and assist the adhesive bonding. Proton insulation between adjacent and electrically linked in-plane cell elements is provided by structural insulation within the central membrane.
