N2 - The sluggish kinetics of oxygen reduction reaction (ORR) affects the massive use of polymer exchange membrane fuel cells (PEMFCs). Therefore, the use of electrocatalysts is required to accelerate the ORR kinetics. Usually, Pt/C electrocatalysts are used for the ORR. Nevertheless, the principal disadvantages of using Pt are its high-cost, low availability, and limited stability. For these reasons, research of more stable and cost effective electrocatalysts with high electrocatalytic activity is important to achieve large-scale power generation. To date, there are significant advances and great opportunities for the design of novel electrocatalysts with high electrocatalytic activity and stability for the ORR through the connection of experimental and theoretical explorations. For these reasons, in this review, combined theoretical–experimental studies for the design of novel Pt-based metallic electrocatalysts for the ORR are revised and analyzed in detail.
