摘　　要：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、AB5型储氢合金为阳极催化剂的DBFC体系,测试表明,CoPc/C阴极在BH4-碱性溶液中不仅表现出优越的氧还原催化活性,而且对BH4-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65mW/cm2,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 BH4-alkaline solutions, but also has no catalytic activity to the BH4-. Therefore, the DBFC is designed without an ion exchange membrane. The test results show that the maximal power density is 65 mW/cm2 and this type of DBFC has good short-term stability.
