以碱金属硼氢化物为燃料的直接硼氢化物燃料电池(DBFC),是一种有发展潜力的移动电源。DBFC阳极过程是一个复杂的H--H0*-H+之间价态转化的电极反应体系,涉及BH 4-的电氧化反应、BH 4-的水解释氢反应与氢的电氧化反应,该过程不仅与电极材料有关,也与反应条件有关。研究能有效抑制释氢的廉价阳极催化材料,是DBFC实用化的关键。本文对近年来报道的DBFC阳极催化材料以及BH 4-在不同阳极材料上的电化学氧化反应机理进行了综述,并归纳出需要深入研究的主要问题。 The direct borohydride fuel cell (DBFC), which is fueled with alkali metal borohydride, is a promising mobile power source. The DBFC anode process is a complex electrode reaction system of valence transition between H - H0 * - H +, involving the electrooxidation of BH 4 -, the hydrodehydrogenation of BH 4 - and the electrooxidation of hydrogen. Not only with the electrode material, but also with the reaction conditions. To study the cheap anode catalytic material that can effectively inhibit the hydrogen release is the key to practical DBFC. In this paper, the electrochemical oxidation reaction mechanism of DBFC anode catalyst and BH 4 -based anode materials reported in recent years are summarized and the main problems that need further study are summarized.
