Abstract
Official abstract text for this publication.
A fuel cell separator 60 having a metal plate and an anticorrosion resin coating layer 55 formed thereon is provided, with which adhesion between the resin coating layer 55 and its counterpart member is further increased and the durability of a fuel cell unit is improved. In forming the fuel cell separator 60 having a separator substrate 50 that is a metal plate and an anticorrosion resin coating layer 55 formed thereon, the resin coating layer 55 is formed such that it has a surface roughness Ra of 0.5 to 13.5 μm. Increasing the surface roughness will produce an anchoring effect, which will improve the adhesive force at the interface. The aforementioned surface roughness Ra can be obtained either with the use of fillers that are mixed into the resin coating layer 55 or with external force applied to the surface of the resin coating layer 55 by means of shot blasting, for example.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel cell separator, comprising: a separator substrate made of a metal plate; and an anticorrosion resin coating layer formed thereon, wherein the resin coating layer is formed on a portion excluding a conducting section of the separator substrate, wherein the resin coating layer has a first surface and a second surface, the first surface of the resin coating layer facing away from the separator substrate, and the second surface of the resin coating…
