This study is an investigation of combinatorial and high throughput screen method for ORR catalyst for alkaline fuel cell. Since the kinetic of alkaline fuel cell ORR is still sluggish, the calling for better catalysts is getting louder. However, the previous screen methods to locating optimal catalytic activity is low efficient. The screen methodology is a combination study of thin film fabrication and electrochemistry where magnetron plasma sputtering has been applied for sample preparation and rotating disk electrode plays an important role in the characterization methodology. The system screened is the palladium (Pd)-3d transitional metal system because Pd shows promising ORR catalytic activity in alkaline media which is comparable with Pt. Previous studies about Pd combined with other 3-d metals exhibit even better activity then single Pd and Pt. Throughout the screen process among the alloys (Pd-Cu, Pd-Co, Pd-Ni, Pd-Fe), we found the Pd50Cu50 has the best catalytic activity.
