摘要

1. Pt: Ru electrodeposit composed of 250 nm spheres distributed in porous carbon matrix. 2. XPS and bulk chemical analysis results confirmed most active deposit had Pt: Ru, 85:15 composition. 3. Bulk chemical analysis results suggest that actual mass loading of deposit was 10-20% that given by electrodeposit coulometry 4. Based on mass effectiveness, a deposit of 0.25 mg/cm~2 was best 5. Miniature fuel cetl with electrodeposited anode catalyst compared very well with that of a large fuel cell with conventional Pt and Pt: Ru black 6. In a large fuel cell, performance of electrodepositcd anode catalyst equivalent to that of JPL Pt: Ru black catalyst at 25% (or less) of the mass loading
