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 silicon-based solid oxide fuel cell (SOFC) with high surface area density in a limited volume is provided. The structure consists of a corrugated nano-thin film electrolyte and a silicon supportive layer on a two-stage silicon wafer through-hole to maximize the electrochemically active surface area within a given volume. The silicon supportive layer is done by boron-etch stop technique with diffusion doping. The fabrication of two-stage wafer through hole combines deep reactive ionic etching (DRIE) and KOH wet etching of silicon for a wafer through hole containing two difference sizes. By these design and fabrication methods, the absolute electrochemically active area can be as high as five times of that of the projected area.

摘要： A reduced cost solid oxide fuel cell having enhanced surface exchange rates and diffusivity of oxide ions is provided. The invention cell includes a first porous electrode and a second porous electrode, where the porous electrodes have a layer of electronically conductive porous non-precious metal, and the porous non-precious metal layer is a gas diffusion layer.

摘要： Solid oxide fuel cells selectively transport oxygen ions through an electrolyte membrane. The maximum oxygen ion transport rate limits the power density of the fuel cell. By ion irradiating the electrolyte membrane and/or the cathode, the oxygen adsorption, dissociation, and incorporation rates can be improved, leading to higher ion transport rates and better fuel cell performance.

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： The present invention provides nano-patterning based on flow of an ion current within an ionic conductor to bring ions in proximity to a microscope probe tip touching a surface of the conductor. These ions are then electrochemically reduced to form one or more features on the surface. Ion current flow and the electrochemical reaction are driven by an electrical potential difference between the tip and the ionic conductor. Such features can be erased by reversing the polarity of the potential difference. Indentations can be formed by mechanically removing features formed as described above. The ions in the ion current can be provided by the ionic conductor and/or by oxidation at a counter electrode.

摘要： Dislocations are fabricated into electrolyte membrane films to increase ion conductivity. Ion and/or electron irradiation causes the growth of vacancy clusters within the thin film and collapsing into Frank dislocation loops that exhibit high ion conductivity. Maximum ion conductivity is accomplished by spatially reorienting the Frank dislocation loops during a following heat-treatment of the membrane. Thereby the dislocation loops form surface-to-surface continuous dislocations along which ions may propagate between membrane surfaces with minimal activation energies. Dislocation densities in the range of 108˜1014 cm/cm3 may be fabricated with conventional irradiation techniques into ceramics such as, for example yttria stabilized zirconia and doped ceria.

摘要： An acoustic sensor and method of using same for determining the position of a tool from a workpiece are disclosed in which a piezoelectric transducer having a curved surface emits a sound wave which strikes the workpiece and is reflected back to the sensor. The sensor and tool are positioned relative to one another so that the workpiece will be near the focal point of the curved surface when the tool is operating. This positioning substantially overcomes the attenuation problems of high frequency sound waves transmitted through air.
