In this presentation, we analyze the economics of hydrogen-, nitrogen-, and carbon-based fuels made by carbon-neutral pathways in a post-fossil world where only water, air, and renewable electricity are available for fuel synthesis, showing that ammonia has the lowest source-to-tank energy cost by a significant margin. With this technoeconomic analysis as motivation, we try to develop a new fuel cell technology of low temperature direct ammonia fuel cells for carbon-neutral transportation. In this presentation, factors that enable a high-performance of direct ammonia fuel cells (DAFCs) are discussed, including high operating temperature, a high-temperature-stable hydroxide exchange membrane, ammonia-tolerant platinum-group-metal (PGM)-free cathode catalysts, and hydrophobic cathode structure. As a result, we achieve a peak power density of 400 mW cm-2 by a hydrophobic spinel cathode and the corresponding design of 75 W DAFC stack, demonstrating the sate of the art in DAFC technology.
