Currently Pt-based metals are the best catalytic electrodes for fuel cells at operating temperatures below 500°C. Pure platinum electrodes suffer degradation of microstructure over time at elevated temperatures due to Ostwald ripening. In this paper, better thermal stability of Pt–Ni nanoporous thin films relative to pure Pt is reported. Based on ab initio calculations, it was found that both the...
Proton exchange membrane fuel cells were fabricated by direct sputter deposition of platinum on the surface of Nafion 117 membranes. A sharp spike in the performance of these sputtered platinum fuel cells was observed at ultra-low platinum thickness values of 5-10nm. Within this narrow thickness range, the power output capability of sputtered platinum fuel cells is several orders of magnitude better...
