Cover Story: Fuel cells are a promising alternative to non-renewable energy production technologies such as petroleum and natural gas. However, cathodic oxygen reduction reaction (ORR) is sluggish under normal conditions. Thus, catalysts must effectively facilitate ORR for fuel cells to operate efficiently. Traditional platinum (Pt) catalysts are often utilized as they exhibit a highly efficient ORR with low overpotential values. However, Pt is an expensive and precious metal, posing economic problems for commercialization. Herein, advances in carbon-based catalysts are reviewed for their application in ORR due to their abundance and low-cost syntheses. This review aims to provide valuable insight into current challenges in fuel cell performance and how they can be overcome using carbon-based materials. View this paper
