直接硼氢化物燃料电池是以硼氢化钾（钠）为燃料的液体燃料电池，具有很好的应用前景。本项目的研究目的是解决目前该领域研究普遍存在的电催化速率与燃料利用效率不能同时提高的矛盾。拟设计并研究Co及Co-M（M=Sn，Ag，Zn等）系列电极材料，研究其对BH4-在碱性溶液中的电化学氧化-水解行为。通过在泡沫镍上原位合成Co基双（多）金属催化剂，避免了碳载体、粘合剂对探索催化机理所带来的复杂性。采用电化学方法及材料微观结构表征手段探讨催化剂对BH4-阳极氧化反应和水解反应的电催化机理，研究催化剂的微观结构对催化剂活性、放电效率、稳定性的影响及催化剂的演变，揭示阳极氧化及水解反应之间的竞争机制，阐明同时提高催化性能及放电效率的有效机制。为优化和完善燃料电池催化剂制备技术、发展新型催化剂提供理论依据，为推进DBFC实际应用提供技术支撑。

Direct borohydride fuel cell is a liquid-type fuel cell using KBH4 or NaBH4 as fuel, and it has good application prospect. The research Objective is to solve the current problems in the field of DBFC— electrocatalysis rate and fuel efficiency cannot be improved simultaneously. We will design and study Co and Co-M (（M=Sn，Ag，Zn...）series electrode materials, study the electrochemical oxidation - hydrolysis behavior of BH4- in alkaline solution. The complexity of carbon support and adhesive on exploring catalytic mechanism are avoided by the synthesis of Co - based bimetallic catalyst in situ on Ni-foam. Adopting electrochemical method and material microstructure characterization methods to investigate the catalyst of BH4 - electro-catalytic mechanism of the anodic oxidation and hydrolysis reaction, the catalyst of microstructure on catalyst activity, the influence of the discharge efficiency, stability and the evolution of the catalyst, reveal the competition between anodic oxidation and hydrolysis reaction mechanism, The effective mechanism to improve the catalytic performance and discharge efficiency will be also clarified. It will provide the theoretical support to optimize and improve the preparation technology of fuel cell catalyst and the development of new catalyst, and it will also provide technical support for the practical application of DBFC.
