Date Apr. 25, 1996Fuel cell stacks comprising stacked separator / membrane electrode assembly fuel cells in which the separators comprise a series of thin sheet platelets, having individually configured serpentine micro-channel reactant gas humidification active areas and cooling fields therein. The individual platelets are stacked with coordinate features aligned in contact with adjacent platelets and bonded to form a monolithic separator. Post-bonding processing includes passivation, such as nitriding. Preferred platelet material is 4-25 mil Ti, in which the features, serpentine channels, tabs, lands, vias, manifolds and holes, are formed by chemical and laser etching, cutting, pressing or embossing, with combinations of depth and through etching preferred. The platelet manufacturing process is continuous and fast. By employing CAD based platelet design and photolithography, rapid change in feature design can accommodate a wide range of thermal management and humidification techniques. One hundred H2-O2 / PEM fuel cell stacks of this IFMT platelet design will exhibit outputs on the order of 0.75 kW / kg, some 3-6 times greater than the current graphite plate PEM stacks.

In implant dentistry, scan templates, also known as scan appliances or radiographic guides, are fabricated according to patients' anatomy, and later on transferred into surgical guides through CT scan, image segmentation, surface reconstruction, CAD modification, and manufacturing. This approach may be also applied to other kinds of surgery. The final manufactured surgical guides can hardly match the actual geometry of the initial scan templates, thus cannot fit well into patients' mouths, which can pose serious risks for surgery.This invention introduces calibration features to design and make a scan template, and accordingly the workflow to perform treatment planning with the template. Calibration features are geometric form features or their patterns. Iterations are utilized to make sure the reconstructed model of a scan template can replicate or match with the calibration features. After treatment planning, calibration features are removed from the model (an optional step), and a surgical guide is designed and fabricated. This invention also includes some special calibration feature designs. The treatment planning workflow is greatly improved with calibration features introduced.
