제목 The synthesis and evaluation of Pt@IrCo/C for bifunctional electrocatalysts for oxygen reduction reaction and oxygen evolution reaction
초록 A fuel cell is an electrochemical energy conversion device that functions by harnessing the chemical energy released from chemical reactions occurring at the anode and cathode and converting it into electrical energy. Currently, ways to reduce or eliminate the use of platinum in fuel cells remain a popular area of research because the high cost of platinum is preventing commercialization. Also, electrolyzing mode of PEMFC to electrically dissociate water to fuel has been required for unitized regenerative fuel cell (URFC) for use in spaceships or satellites. Our work focused on enhancing the activity of platinum used by creating a platinum shell on iridium-cobalt alloyed core. The decision to use iridium-cobalt alloyed core was used instead of conventional metal core supports was made with the idea that too strong interaction between platinum and iridium may be altered by iridium-cobalt core, improving its oxygen reduction activity and oxygen evolution activity.
