Outline of Final Research Achievements

The fabrication of ammonia synthesis cell was achieved by using Si3N4 pellet as nitride ionic conductor and Mg doped Al2O3 plate as protonic conductor. In this case, these pellet and plate were assembled by using palladium paste. In addition, the blocking electrode type ammonia synthesis cell was also fabricated by using Sr0.5Ce0.4Y0.1O3-d series oxide. The ammonia synthesis tests were performed by using these cells. However the obvious data, which suggest the possibility of ammonia synthesis, were not obtained. This result suggested the additional necessity of the optimization of electrode material, ionic conductor and the shape control of these materials.
