Proton exchange membrane fuel cells (PEMFCs) are expected to drive large-scale markets such as fuel cell vehicles. However, their widespread adoption has been hindered by the high cost associated with the large amount of platinum (Pt) required as a catalyst for the oxygen reduction reaction (ORR) at the cathode. Therefore, the development of Pt-free catalysts is of great importance. In this study, we performed electrochemical evaluation of a novel carbon material, quenching carbon (Q-carbon), to investigate its potential as a Pt-free catalyst for ORR.
