研制一种无膜型直接硼氢化物燃料电池(DBFC).循环伏安测试发现FeCoPc2在碱性溶液中对氧还原具有催化作用.稳态极化曲线表明,由于FeCoPc2结构具有较强的共轭效应以及Fe、Co在催化中的协同作用使它比FePc、CoPc具有更强的氧还原能力,并获得了110mW/cm2的功率密度.恒电流放电测试表明该燃料电池性能具有良好的稳定性.

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.
