Abstract

In this paper,a membraneless direct borohydride fuel cell was investigated. Cyclic voltammograms of FeCoPc₂-modified glassy carbon electrode in the alkaline solution show that FeCoPc₂ was active for oxygen reduction reaction. In addition, the steady-state polarization curve tests indicate that FeCoPc₂ had better activity than FePc,CoPc or FePc+CoPc, which is due to its conjugated effect and synergistic effect of Fe and Co. Finally, a maximum power density of 110 mW/cm² was attained, and the 25-day life test shows that the direct borohydride fuel cell had a good stability.
