| Outline of Final Research Achievements |
In order to reduce Pt amount of a catalyst layer in our miniature fuel cells, novel Pd-Pt catalyst formation technique was developed. Slight Pt deposition was realized by following procedure. At first, atomic layer of Cu was deposited on Pd surface by UPD (underpotential deposition). Then, the Cu was replaced to Pt by SLRR (Surface Limited Redox Replacement). Pt amount was measured by ICP-AES. Though the estimated Pt amount was less than 0.01mg/cm2 in the Pd-Pt catalyst, competitive fuel cell performance to conventional pure Pt catalyst was obtained. Furthermore, the Pd-Pt catalyst showed high CO tolerance.
