Schematic of the nanocomposite cathode material consisting of Nafion-coated carbon black (CB)-containing platinum nanoparticles (PtNP). The PtNPs catalyze the reduction of protons (H+) and oxygen (O2) to water (H2O). i,ii) Field emission scanning electron (FESEM) and iii,iv) transmission electron (TEM) micrographs of Nafion-coated platinum nanoparticle-coated carbon black-modified cathode material (PtNP-CB/Nafion) after v) 1 day and vi) 60 days (FESEM only).
