抄録

Chromium-based electrocatalysts which were prepared using an R.F. sputter with CrC target under Ar or Ar + N<SUB>2</SUB> atmosphere with or without heating a substrate at 1073 K were evaluated as a cathode of polymer electrolyte fuel cells (PEFCs). Heating the substrate during the sputtering was found to be very useful to enhance the catalytic activity for oxygen reduction reaction (ORR). It is considered that nitride (CrN) and/or carbonitride (Cr<SUB>2</SUB>C<SUB>0.39</SUB>N<SUB>0.61</SUB>) may have high catalytic activity for the ORR.
