A machining apparatus includes an apparatus body and a setting jig. The setting jig has a frame body including openings to expose molding regions, which are to be molded by the apparatus body, of the sheet material, and a restraining portion to restrain a periphery of the molding regions. The apparatus body includes a support member that supports the setting jig at a position where the molding regions are disposed between an upper die and a lower die, and a first urging member to urge the support member toward the upper die so as to separate the molded body from the lower die, with the upper die disengaged from the lower die.

Separator machining apparatus and separator machining method

A fuel cell separator capable of surely discharging produced water, and a method and apparatus for producing the same. The fuel cell separator is formed in a wave shape with recesses and projections alternately arranged in a first direction, the recesses forming reactant gas channels together with a membrane electrode assembly and the projections abutting the membrane electrode assembly, in which on a surface of the fuel cell separator that is adapted to face the membrane electrode assembly, a plurality of first grooves extending in the first direction along the corrugation of the recesses and projections is disposed at intervals from each other in a second direction orthogonal to the first direction, and a second groove extending in the second direction and communicating with the plurality of first grooves is disposed in the bottom portion of each recess.

A manufacturing method for a fuel cell separator includes preparing a separator member in which an uncured thermosetting resin layer is provided on a surface of a core member, as a preparation step; and pressing the separator member while heating the separator member so that a gas flow passage is formed in the separator member while the uncured thermosetting resin layer is cured, as a hot-press step.

Manufacturing method for fuel cell separator

There are included a preparing step of preparing a separator base member having a core member of which surfaces are coated with a coating material having a higher radioparency than that of the core member; a press-forming step of press-forming the separator base member in a predetermined shape; and an examining step of examining the separator base member after the press-forming step using an X-ray having an output at which the X-ray passes through the coating material.

An exhaust gas control apparatus for an engine and a method for producing the same are provided. The exhaust gas control apparatus includes a valve portion, an absorption portion, and a catalyst portion. The valve portion includes a valve that opens/closes a main exhaust passage. The absorption portion includes a hydrocarbon-absorbent that absorbs hydrocarbons. The catalyst portion includes a three-way catalyst that purifies exhaust gas. The valve portion, absorption portion, and the catalyst portion are independent of each other. The valve portion, the absorption portion, and the catalyst portion are connected to each other in series. With this configuration, any individual component can be replaced with another corresponding component that achieves a required level of performance while minimizing the number of other components.

A catalyst container of a catalytic converter is of a double-pipe structure wherein an outer periphery of an inner pipe and an inner periphery of an outer pipe are fittingly superposed on each other. The catalyst container has a catalyst installing portion, tapered cone portions extending from the catalyst installing portion with a gradually decreasing diameter, and straight connecting portions extending from smallest-diameter regions of the cone portions to the ends to be connected with connecting pipes upstream and downstream of the catalytic converter. Holes maybe formed in the cone portions of one of the inner or outer pipes to permit fluids to be displaced from the space therebetween. Such a catalyst container has sufficient rigidity and radiated noise suppression properties and thus can be reduced in weight by being thinned.

A fuel reformer suited for mounting on a vehicle is provided. A raw material gas containing methanol and water is vaporized at a vaporization section The vaporized gas flows horizontally to a reforming section with monolithic catalyst The reforming section is divided into two sides, a front side and a rear side with an interconnecting pipe bent at 180 degrees, for connecting the front and rear sides. By making the material gas flow horizontally, even when the reformer is mounted to a vehicle which has a larger space in its horizontal direction than in its vertical direction, especially a small passenger car, the contact time period between gas and catalyst can be extended. By bending the reforming section by 180 degrees, the size of the reformer can be reduced so that the reformer is suited for mounting on a vehicle having limited space. Because the vaporization section and the CO reducing section can be placed adjacent to each other, by using heat generated at the CO reducing section, the heat loss during pre-heating of the methanol and water can be reduced.
