Performance of direct formic acid fuel cell using transition metal-nitrogen-doped carbon nanotubes as cathode catalysts
Fe- and Co-nitrogen-doped carbon nanotube catalysts prepared exhibit higher formic acid tolerance than conventional Pt/C catalyst. The highest maximum power density achieved by single DFAFC with Co-NCNT cathode catalyst, which is 142.4 mW cm(-2) at 60 degrees C and 5-M formic acid concentration. This value is higher than that achieved by DFAFC with Pt/C cathode catalyst under similar operating condition.
