Direct formic acid fuel cells (DFAFCs) have gained immense importance as a source of clean energy for portable electronic devices. It outperforms other fuel cells in several key operational and safety parameters. However, slow kinetics of the formic acid oxidation at the anode remains the main obstacle in achieving a high power output in DFAFCs. Noble metal-based electrocatalysts are effective, but are expensive and prone to CO poisoning. Recently, a substantial volume of research work have been dedicated to develop inexpensive, high activity and long lasting electrocatalysts. Herein, recent advances in the development of anode electrocatalysts for DFAFCs are presented focusing on understanding the relationship between activity and structure. This review covers the literature related to the electrocatalysts based on noble metals, non-noble metals, metal-oxides, synthesis route, support material, and fuel cell performance. The future prospects and bottlenecks in the field are also discussed at the end.
直接甲酸燃料电池（DFAFCs）作为便携式电子设备的清洁能源来源已变得极为重要。它在几个关键的运行和安全参数方面优于其他燃料电池。然而，阳极处甲酸氧化的缓慢动力学仍然是DFAFCs实现高功率输出的主要障碍。基于贵金属的电催化剂是有效的，但价格昂贵且容易发生一氧化碳中毒。最近，大量的研究工作致力于开发廉价、高活性和持久的电催化剂。在此，介绍了DFAFCs阳极电催化剂开发的最新进展，重点是理解活性与结构之间的关系。这篇综述涵盖了与基于贵金属、非贵金属、金属氧化物、合成路线、载体材料和燃料电池性能的电催化剂相关的文献。最后还讨论了该领域的未来前景和瓶颈。
