The 21st century is characterised by the rush to tackle climate change by resorting to sustainable development. When it comes to energy, new technological opportunities have been ceased, including the promising fuel cell, an electrochemical device that offers a clean and environmentally friendly alternative to conventional combustion engines. Their use could revolutionise several sectors, from transport to stationary power generation. However, for them to spread on a large scale, several difficulties must be overcome, including the development of an efficient, selective catalyst without rare materials that facilitates the oxygen reduction reaction (ORR) and enables good cell performance and durability. The ORR occurs at the cathode of the fuel cell and is regarded as the rate-determining step due to its sluggish kinetics.
