In this program we developed a direct ammonia fuel cell to efficiently convert ammonia to electricity for electric vehicles and other applications. The team developed new materials, including low-cost, high-performance hydroxide exchange membranes that can maintain stability near 100°C and novel ammonia oxidation catalysts. Hydrolite developed a Direct Ammonia membrane-electrode assembly (MEA) featuring advanced membranes and electrocatalysts, as well as designing and building the prototype direct ammonia fuel cell system for fuel, air and water supply and temperature control at operating temperatures above 100℃.
