High-entropy catalyst lets ammonia fuel cell reach world-class power and durability

AI Insight

Researchers from KAIST and a collaborative team have developed a high-entropy catalyst that enables direct ammonia fuel cells to achieve high power output and long-term operational stability. The technology bypasses the conventional need to convert ammonia into hydrogen before use, allowing ammonia to serve directly as a fuel source. The high-entropy catalyst approach is reported to deliver performance and durability metrics competitive with leading existing fuel cell systems.


Ammonia is easier to store and transport than hydrogen, making this technology a potentially practical pathway toward carbon-free power generation at scale. Successful commercialization could accelerate the transition to a hydrogen economy by reducing infrastructure barriers associated with pure hydrogen fuel.


As ammonia gains attention as a next-generation energy source capable of overcoming the limits of hydrogen storage and transport, KAIST and a joint research team have developed fuel cell technology that directly uses ammonia as fuel while achieving world-class performance and stability. This achievement is regarded as a core technology that will accelerate the commercialization of the next-generation hydrogen economy and carbon-free power generation.
