Abstract
A separator of this invention is so constructed that a plurality of protrusions are implanted in a substrate which forms a reactive chamber of a fuel cell. The substrate has a multiple layered structure in which a single side or both sides of a mesh foundation are covered with resin layer and contains through holes at positions corresponding to each of the protrusions. Each of the protrusions is formed by allowing black lead ink applied on the single side or both sides of the substrate to invade each through hole. Consequently, the substrate can be formed to be super thin, lightweight and the respective protrusions can be easily formed at low cost.
Claims9
A manufacturing method for a conductive plate comprising steps of:
- preparing a mesh foundation;
- forming a substrate by covering said mesh foundation with a resin layer, said resin layer being formed by coating a single side or both sides of said mesh foundation with resin or impregnating the mesh foundation with resin and having the through holes at predetermined positions and;
- forming protrusions protruding from a single side or both sides of the substrate at positions corresponding to the through holes in said resin layer by coating the single side or both sides of said substrate with said black lead paint;
- and
- hardening said protrusions formed on said substrate.
