直接硼氢化物燃料电池(DBFC)因其高的理论电压和阳极电氧化速率而引起广泛的关注.在本研究中,建立了以碳载钴酞菁(CoPc/C)为阴极催化剂、AB_5型储氢合金为阳极催化剂的DBFC体系,测试表明,CoPc/C阴极在BH_4-碱性溶液中不仅表现出优越的氧还原催化活性,而且对BH_4-没有催化活性,因此,在此体系中的DBFC可以不使用任何离子交换膜.实验中测得的最大功率密度为65 mW/cm_2,并具有良好的稳定性.

Direct borohydride fuel cell (DBFC) has attracted significant attention due to its high theoretical voltage and fast anodic electrooxidation rates. A DBFC using a cobalt phthalocyanine supported on active carbon (CoPc/C) catalyzed air cathode and a hydrogen storage alloy-catalyzed anode was presented in this paper. It is found that CoPc/C cathode not only demonstrates considerable electrocatalytic activity for oxygen reduction in BH_4-alkaline solutions, but also has no catalytic activity to the BH_4-. Therefore, the DBFC is designed without an ion exchange membrane. The test results show that the maximal power density is 65 mW/cm~2 and this type of DBFC has good short-term stability.
