A fuel cell stackincludes a fuel cell stack, and an end plateplaced at an end of the fuel cell stack. The end plateincludes a metallic plate-like body, and a resin layerformed on a surfaceof the plate-like body. The plate-like bodyincludes flow holesfor a reactant gas and a cooling medium, and a stripe-shaped protrusionprotruding from the surfaceand which divides the surfaceinto an inner area containing the flow holesand an outer area outside the inner area. The protrusionincludes a vertical portionprotruding from the surface, and a jutted portionjutted from a distal end of the vertical portiontoward the inner area. The resin layeris formed in the inner area to cover a surfaceof the vertical portionfacing the inner area as well as at least part of the jutted portion

Fuel cell end plate with resin layer and protrusion

A fuel cell stack includes a stack; a case that accommodates the stack; and end plates arranged in the outside of a stacking direction and formed with fluid flow path holes penetrating in the stacking direction an accommodating groove for accommodating a seal member for sealing a part between the accommodating groove and the case. The end plates have a metal member formed with the fluid flow path holes, a first recess and a second recess that continues to the first recess, and a resin layer that continuously covers an inner peripheral wall surface of the fluid flow path holes, a surface that faces the stack, a part that includes at least an outer peripheral side end in the first recess, and the second recess, in the metal member. The resin layer is formed with the accommodating groove in a surface corresponding to the end surface of the case in a part covering the part that includes at least the outer peripheral side end in the first recess. The second recess accommodates a part of the resin layer to restrict the resin layer.

Fuel cell stack

A fuel cell stack comprises a stacked body, an end plate and a case configured such that the stacked body is placed therein. The end plate is arranged to cover an end face of the stacked body in a stacking direction and an end face of the case in the stacking direction and is fastened to the end face of the case. A placement groove is formed in at least one surface out of two surfaces of the end plate and the case opposed to each other, such that a seal member is placed in the placement groove. The end plate includes a resin layer formed to continuously cover an inner circumferential wall surface of the fluid flow path hole, a surface of the end plate opposed to the stacked body, and an outer circumferential side end of the placement groove.

Provided is a boot seal for a variable compression ratio engine having an inner layer free from tears or creases. The boot seal comprises a boot body having a cylinder-attaching part, a crankcase-attaching part and a connecting part for connecting these parts, and a rigid plate disposed in at least one of the cylinder-attaching part and the crankcase-attaching part and having a through hole. The boot body comprises an outer layer formed by injection molding a rubber material, and an inner layer formed of fluorine-containing rubber. An injection gate for the outer layer is located at a portion of the outer layer opposing the rigid plate. Both an outer surface and an inner surface of at least a portion of the rigid plate having the through hole are covered with the rubber material supplied from the injection gate.

Boot seal for variable compression ratio engine

A battery cover member () of the present invention includes a metallic electrode terminal (), a metallic cover member () having through holes (), and an insulating resin member (), in which the electrode terminals inserted into the through hole and the cover member are integrally bonded together by the insulating member, wherein at least a sealing area () of the electrode terminal that adheres to the insulating member is formed as a columnar shape or an elliptically columnar shape.

Battery cover member

A high thermal conduction insulator exhibiting thermal conductivity, insulating properties and heat radiating properties is produced by supplying a molding material composed of an insulating resin, a diamagnetic material powder and a paramagnetic material (inclusive of ferromagnetic material) powder, and exhibiting fluidity into a mold, and applying a magnetic field to the molding material in the mold to orient clusters, each being composed of diamagnetic material particles of the diamagnetic material powder, which are joined together like a chain, along directions of lines of a magnetic force, and draw the paramagnetic material (inclusive of ferromagnetic material) powder with the magnetic force along one of mold surfaces of the mold, thereby forming a heat radiating layer. Heat transmitted from a facing member to one surface of the insulator is speedily transmitted to the other surface thereof via the clusters, and is effectively radiated from the heat radiating layer existing in the other surface.
