| Description |
In situ polymerization of 3,4-ethylenedioxythiophene with sol–gel-derived mesoporous carbon (MC) leading to a new composite
and its subsequent impregnation with Pt nanoparticles for application in polymer electrolyte fuel cells (PEFCs) is reported. The
composite exhibits good dispersion and utilization of platinum nanoparticles akin to other commonly used microporous carbon
materials, such as carbon black. Pt-supported MC–poly(3,4-ethylenedioxythiophene) (PEDOT) composite also exhibits promising
electrocatalytic activity toward oxygen reduction reaction, which is central to PEFCs. The PEFC with Pt-loaded MC-PEDOT
support exhibits 75% of enhancement in its power density in relation to the PEFC with Pt-loaded pristine MC support while
operating under identical conditions. It is conjectured that Pt-supported MC–PEDOT composite ameliorates PEFC performance/
durability on repetitive potential cycling.
