This study investigated the potential of chromium carbide-derived carbons as support materials for polymer electrolyte membrane fuel cell catalyst. The results showed that the synthesis temperature significantly influenced the carbon crystallographic structure and pore characteristics, indicating the suitability of the studied carbons as catalyst supports.
Chromium carbide-derived carbons were synthesized at various temperatures as possible support materials for polymer electrolyte membrane fuel cell catalyst. The physicochemical characterization data demonstrated that synthesis temperature applied affects significantly the carbon crystallographic structure, including graphitization ratio, and micropore and mesopore volume values. The electrochemical measurements in KOH and HClO4 revealed capacitive behaviour of materials and suitability of studied carbons as catalyst supports.
