Sumario:The article reports on palladium (Pd)-titanium (Ti) and Pd-cobalt (Co)-silver (Au) electrocatalysts as a Replacement for platinum (Pt) for oxygen reduction in proton exchange membrane fuel cells. Catalysts Pd-Co-Au and Pd-Ti show essentially equal or slightly better performance than the more expensive Pt currently used for the oxygen reduction reaction in proton exchange membrane fuel cells (PEMFC). The article demonstrate that the previously described high throughput screening method based on scanning electrochemical microscopy is indeed a good predictor of electrocatalyst performance in a PEMFC.
