Fuel cells are the best alternatives to meet the growing energy demand with no pollution. Nanomaterials play a significant role in applications as electrocatalysts for fuel cells. Among them, nanomaterials of platinum (Pt) have been mainly used as electrocatalytic material in fuel cells for a long time due to its excellent electrochemical properties towards oxygen reduction reaction (ORR). Bearing the limitations like scarcity and higher cost, Pt nanomaterials have to be replaced by novel materials for ORR. Carbon-based nanomaterials are in research owing to their electrocatalytic activity at par with that of Pt nanomaterials, which are applied as bifunctional electrocatalyst, transition metal oxides and also as supports for various dopants. This article focuses on recent research in nanomaterials for ORR in fuel cells.
