Abstract: Provided is a method of producing an inorganic fiber mat, the method enabling efficient adhesion of an aldehyde scavenger to an inorganic fiber mat while preventing the aldehyde scavenger from scattering around. The method of producing an inorganic fiber mat includes a fiber collection step of applying a binder to inorganic fibers and accumulating in a mat-like shape on a conveyor line to form an inorganic fiber web, a binder-curing step of heat-curing the binder applied to the inorganic fiber web to form an inorganic fiber mat, and an aldehyde scavenger application step of applying an aldehyde scavenger to the inorganic fiber mat, in which the aldehyde scavenger application step involves spraying the aldehyde scavenger in a form of droplets having an average diameter of 1 to 50 ?m on a front side of the inorganic fiber mat and sucking from a back side of the inorganic fiber mat.

Abstract: In order to inhibit a gasket (1) adhered to a plate body such as a separator (3) of a fuel battery or the like from being adversely affected by an elution component from an adhesion means, the gasket has a main lip (11), a back surface seal portion (12) formed in a back surface of the main lip and closely contacted with a separator (a plate body to be adhered) (3), an adhesion portion (14) arranged in a position in an opposite side to a space (S) to be sealed with respect to the back surface seal portion (12) and adhered to a bottom portion (31a) of a gasket installation groove (31) of the separator (3) via an adhesive agent (2), and an adhesive agent sump (15) formed between the back surface seal portion (12) and the adhesion portion (14) and holding an excess adhesive agent (2a).

Abstract: Notches 23e are filled with part of an elastic material that is injection-molded in a region containing the notches 23e, so that a plate member 23b is taken in by the notches 23e through the repulsive force of the elastic material. Thus, the plate member 23b is secured. Further, the elastic material filling the notches 23e enlarges the joined portion between the plate member 23b and the gasket 24b. Accordingly, the gasket 24b is firmly joined to the surface of the plate member 23b, and can be prevented from being lifted up from the plate member 23b. Thus, the plate member 23b is firmly secured to the separator main body 25.

Abstract: A resin film is provided wherein distortions generated at ear portions of films at shorter sides of a resin film coated heat insulating/sound absorbing material can be eliminated. The front and rear surfaces and both side surfaces in the direction of longer sides of the inorganic fiber mats are covered with band shaped resin films in a state that a predetermined spacing is provided between the mats, and the resin films are cut at a portion between the mats by a cutting blade along a direction of shorter sides in a state that the films are pressed by a pressing member, the resin films are pressed by the pressing member having film setting portions at both ends of a bottom surface thereof, whereby the slopes of the film setting portions prevent the ear portions of the resin films at the cutting portion from spreading sideways.
