The formed Pt catalyst showed the average particle size of 4.1 nm. This Pt catalyst was applied to a polymer electrolyte membrane fuel cell (PEMFC). The PEMFC showed an open voltage of 0.85 V and a maximum output power density of 216 mW/cm2 %K platinum (Pt) catalyst %K proton exchange membrane fuel cell (PEMFC) %K in-liquid plasma %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5333016/
