    摘要： An improved two-step replication process for fabrication of porous metallic membranes is provided. A negative of a porous non-metallic template is made by infiltration of a liquid precursor into the template, curing the precursor to form a solid negative, and removing the template to expose the negative. Metal is deposited to surround the exposed negative. Removal of the negative provides a porous metallic membrane having pores which replicate the pores of the original template membrane. The negative is kept immersed in a liquid at all times between removing the template and depositing the metal. This immersion eliminates damage to the negative that would be incurred in drying the negative out between these processing steps. Another aspect of the invention is metallic membranes prepared according to the preceding method. For example, metallic membranes having pores smaller on one side than on the other side of the membrane are provided.

    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.

    摘要： A membrane electrode assembly (MEA) having a nano-tubular patterned structure and having solid (instead of porous) electrode layers is provided. Increased mechanical strength is provided by the use of solid electrode layers. The electrode layers are sufficiently thin to permit the flow of reactants to the electrolyte. The nano-tubular pattern includes multiple closed-end tubes and increase the reaction area to volume ratio of the MEA. The nano-tubular pattern also serves to increase mechanical strength, especially in a preferred honey-comb like arrangement of the closed-end tubes. A catalyst is preferably disposed on the anode and cathode surfaces of the MEA, and is preferably in the form of separated catalyst islands in order to increase reaction area. MEAs according to the invention can be fabricated by layer deposition on a patterned template. Atomic layer deposition is a preferred deposition technique.

    摘要： A membrane-electrode assembly for a solid oxide fuel cell is provided. The membrane-electrode assembly has a substantially constant-thickness electrolyte layer. The electrolyte layer distinguishes first and second electrolyte layer surfaces arranged in a three-dimensional pattern with opposite first and second planar pattern surfaces. The three-dimensional pattern has a first set of features extending inward from the first planar pattern surface. It has a second set of features extending inward from the second planar pattern surface opposite to the first planar pattern surface. A first electrode layer is adjacent and conforming to the first electrolyte layer surface. At least one mechanical support structure exists within some or all of the second set of features. A second electrode layer is adjacent and conforming to the second electrolyte layer surface and to at least one mechanical support structure. The membrane-electrode assembly is deposited on a substrate with at least one through hole.
