Abstract

There is provided a terminal plate comprising a plate stacked body including a first metal plate that is electrically conductive and has a current collecting terminal for power collection, and second metal plates that have higher corrosion resistance than the first metal plate and are placed across the first metal plate. A first gasket is mounted to the second metal plate and is provided to surround at least a gas flow hole used for supply of a gas on the second metal plate-side. A second gasket is mounted to the second metal plate and is provided to surround a cooling water flow area which communicates with a cooling water flow hole used for supply of cooling water on the second metal plate-side. The current collecting terminal is protruded from a plate outer circumferential end of the first metal plate in a direction from one flow hole of the gas flow hole and the cooling water flow hole toward the plate outer circumferential end of the first metal plate. This configuration enables the current collecting terminal to be cooled down from the second metal plate-side via the first metal plate.

Abstract

In a fuel cell separator and the like, a technology for reducing the separation of a flow path rib which rectifies the flow of a fluid is desired. A separator used in a fuel cell is provided, the separator including: a separator main body that includes a fluid flow region through which a reactive gas or a coolant flows, a through-hole through which the reactive gas or the coolant flows, and a connection portion which connects the fluid flow region and the through-hole; and a flow rectifying portion that is arranged by being adhered on the connection portion and that rectifies flow of the reactive gas or the coolant between the fluid flow region and the through-hole, where the flow rectifying portion includes a plurality of protruded portions and a coupling portion which is thinner than the protruded portions and which couples the protruded portions.

Abstract

A separator for a fuel cell, to be disposed opposing to a membrane electrode assembly, is provided. The separator includes a separator central area portion opposing to a center area of the membrane electrode assembly that concerns generating power, an outer edge portion located in an outer edge of the separator central area portion, a rubber molded body made of rubber, the rubber molded body being formed in the outer edge portion by die-casting a die-casting rubber material using die, and an adhesive layer formed in the outer edge portion, for adhering the rubber molded body to the outer edge portion. The adhesive layer is formed over an adhesive layer area that includes and is larger than an area where the rubber molded body is die-casted in the outer edge portion. Thus, a disadvantage due to burrs which are generated when die-casting the rubber molded body can be reduced.

Abstract

A vibration damping rubber bushing that has excellent vibration damping property and anticorrosive property, can strongly fix to a supporting component, and has excellent fall off-preventing property in using the same. The vibration damping rubber bushing includes an inner sleeve, an cuter sleeve, and a rubber elastic body interposed between the inner sleeve and the outer sleeve, the inner sleeve, outer sleeve and rubber elastic body being integrally formed, wherein a coating film of an aqueous paint including an amino-modified epoxy resin as a binder is formed on a circumference of at least the outer sleeve selected from the inner sleeve and the outer sleeve.
