Abstract

Ammonia is a promising zero-carbon alternative fuel. Direct ammonia fuel cells (DAFCs), as an efficient ammonia-fueled power system, have an extremely high application value in the field of transportation for decarbonization. Metals are essential components for catalysts and electrolytes in DAFCs, with catalysts being critical to their overall performance. Currently, ammonia-fueled solid oxide fuel cells with Ni-based catalysts have reached peak power densities exceeding 1000 mW·cm⁻². In the case of anion exchange membrane fuel cells, platinum-group metal catalysts can achieve a peak power density of 410 mW·cm⁻². Despite these advancements, further development of more efficient, stable, and cost-effective catalysts is necessary to meet the demands for high efficiency and power density in transportation power systems. This review comprehensively summarizes the recent advancements of metal materials in DAFCs, as well as the potential applications of DAFCs in the transportation sector.

直接氨燃料电池的最新进展：从材料到运输应用

氨是一种很有前途的零碳替代燃料。直接氨燃料电池（DAFCs）作为一种高效的氨燃料动力系统，在交通运输脱碳领域具有极高的应用价值。金属是DAFCs中催化剂和电解质的重要组成部分，催化剂对DAFCs的整体性能至关重要。目前，使用镍基催化剂的氨燃料固体氧化物燃料电池的峰值功率密度已经超过1000 mW·cm−2。在阴离子交换膜燃料电池中，铂族金属催化剂的峰值功率密度可达410 mW·cm−2。尽管取得了这些进展，但为了满足交通动力系统对高效率和功率密度的要求，需要进一步开发更高效、稳定和具有成本效益的催化剂。本文综述了金属材料在DAFCs中的最新研究进展，以及DAFCs在交通运输领域的潜在应用。图形抽象
