| Outline of Final Research Achievements |
Ammonia has a very important role on energy storage and transport in a new energy system. For the purpose of developing a next-generation alkaline ammonia fuel cell, the ammonia oxidation activity of Pt black and Pt oxide black was investigated. The ammonia oxidation activity of the Pt oxide black was increased by electrochemical reduction. The activity was also improved by changing the mass ratio of Pt/anion-exchange resin in the electrocatalyst layer. The increase of three-phase boundary was interpreted as the key factor in the improvement of ammonia oxidation activity. Both the H2/O2 and NH3/O2 fuel cells using Pt oxide black electrochemically reduced as anode catalyst showed the superior discharge performance compared with the fuel cells using the Pt black or Pt oxide black without reduction. The reaction mechanism of the ammonia oxidation on the former catalyst was different from those on the two latter catalysts.
