    摘要: A device for altering a feed stock is made of a structure for passage of a feed stock. The structure can be either an extruded unibody structure, or a nested structure. The structure has an interior and an exterior section, and a longitudinal axis, and walls defining two sets of open-ended passages which extend along the longitudinal axis. The two sets of passages have different cross sectional shapes or dimensions with respect to each other. When the structure is nested, at least one set of channels have a cross section in the shape of truncated arcs. A method for making the unibody structure involves extruding a plasticized raw material mixture through a die, followed by heat-treating. A method of altering a feed stock which involves passing a feed stock into the device through one set of passages to cause an altering of the feed stock, and thereafter passing the output stream into and through the other set of channels to the exterior of the device.

    摘要: According to one aspect of the present invention the fuel cell device includes an electrolyte sheet. The electrolyte sheet has a substantially non-porous body of a varied thickness, a relatively smooth surface and a more textured surface with multiple indentations therein, wherein the thickest part of the electrolyte sheet is at least 0.5 micrometers greater than the thinnest part of said electrolyte sheet. The side of the electrolyte sheet with a relatively smooth surface is subjected to the predominately tensile force and the other, more textured surface subjected to predominately compressive force. According to one embodiment, the fuel cell also includes one cathode disposed on the more textured side of said electrolyte sheet at least at least one anode disposed opposite the cathode on the relatively smooth side of aid electrolyte sheet. According to one embodiment, the relatively smooth side of the electrolyte sheet is the fuel facing side and the more textured side is the air-facing side.
