METHOD FOR JUDGING ADHESION OF DISCONTINUOUS COATING LAYER FORMED OF IN SURFACE OF METAL- BIOPOLAR PLATE FOR A FUEL CELL |
摘要 |
Disclosed is a method for judging the adhesion of a discontinuous coating layer formed on the surface of a metallic biopolar plate for a fuel cell. The method for judging the adhesion of the discontinuous coating layer formed on the surface of the metallic biopolar plate for a fuel cell according to the present invention comprises: a step for forming the metallic biopolar plate with the discontinuous coating layer containing at least one among conductive metallic particles or conductive intermetallic compounds on the surface of a metallic material for a biopolar plate, and an oxide film formed on the rest surface of the metallic material for a biopolar plate where the discontinuous coating layer is not formed (a); a step for moving a pressing unit at predetermined distances in a state where the pressing unit presses the continuous coating layer with critical load (b); a step for judging the remaining rate of nanoparticles by a scanning electron microscope (SEM) after the pressing unit moves (c); and a step for judging the adhesion fault of the continuous coating layer by comparing a predetermined remaining rate with the judged remaining rate (d). [Reference numerals] (AA) Start;(BB) End;(S110) Preparing a metallic dividing plate including a nanoparticle discontinuous coating layer and an oxide film on the surface of a metallic base material;(S120) Moving a pressing unit at predetermined distances in a state where the pressing unit presses the discontinuous coating layer with separation critical load;(S130) Judging the remaining rate of nanoparticles on the discontinuous coating layer;(S140) Judging the adhesion fault of the discontinuous coating layer by comparing a predetermined remaining rate with the judged remaining rate |
