碩士 === 長庚大學 === 化工與材料工程學系 === 106 === In this experiment, the effect of the anode catalyst of direct ammonia fuel cell on the electrochemical oxidation reaction of ammonia was discussed. The metal clusters were deposited on the glassy carbon electrode by means of electric pulse deposition to observe the reaction to ammonia. A direct ammonia fuel cell(DAFC), platinum catalyst for ammonia reaction may be the best, while used as an anode catalyst. There is a poison phenomenon, a nitrogen atom in the process of formation of nitrogen oxide is adsorbed on the catalyst surface, resulting in low current density. The use of electrodeposition of zinc metal on platinum metal, may change the surface of the electronic properties and thus affect the surface - molecular interaction.
