The use of carbon cathode catalysts in polymer electrolyte fuel cells instead of the current platinum catalysts is attracting increasing attention. We claim that two factors are important for enhancing the activity of carbon cathode catalysts in the oxygen reduction reaction (ORR): the formation of a nanoshell structure and co-doping with boron and nitrogen. Herein, we investigate the preparation...
This study reports the synergistic improvement of the oxygen reduction reaction (ORR) activity of a carbon catalyst prepared from a phenol–formaldehyde resin by simultaneous incorporation of Cu and Fe phthalocyanines. This carbon catalyst exhibited higher ORR activities than those prepared with either Cu or Fe phthalocyanines, with an approx. 28-fold maximum ORR current enhancement observed when Cu/Fe = 75:25...
The effects of graphite oxide (GO) additions on the oxygen reduction reaction (ORR) activity of carbon alloy catalysts were examined in order to develop high performance cathode catalysts for polymer electrolyte fuel cell. Different amounts of GO were mixed with a carbon alloy precursor consisting of phenolic resin and phthalocyanine iron, followed by carbonization at 800°C. Thermogravimetry revealed...
