Researchers at KAIST have developed a new catalyst for protonic ceramic fuel cells that allows ammonia to be used directly as a fuel. This technology addresses previous issues with material degradation and slow reaction rates, enabling more stable and efficient electricity generation without carbon emissions. By using a high-entropy oxide catalyst and metal nanoparticles, the team achieved a power density of 2.04 W per square centimeter at 700 degrees Celsius. This breakthrough could simplify the hydrogen economy by using ammonia as a more practical medium for storing and transporting energy.
