| Research Abstract |
Corrosion behavior of stainless steels was studied in order to determine suitable chemical compositions for use as bipolar plates of polymer electrolyte membrane fuel cells. The selected stainless steels were subjected to surface analysis after cell operation, which enabled one to estimate the operating chemical situation. The problem of contact resistance due to passivation was resolved by the newly proposed method : electrophoretic deposition of composite of nano-sized TiN and elastic styrene butadiene rubber particles. Thus the cell using the developed stainless steel bipolar plates performed comparably to graphite employing cell.
