High yield hydrogen peroxide production in a solid polymer electrolyte electrolyzer with a carbon fiber coated mesh substrate

Abstract We investigated high-yield hydrogen peroxide generation using a membrane electrode assembly (MEA) with a carbon fiber (CF)-coated mesh substrate in a solid polymer electrolyte electrolyzer. Current efficiency (52%) and power consumption (0.3 Wh g− 1) for this MEA were 1.5 times higher and 2 times lower at − 0.1 V vs. Ag/AgCl than those of reported values. These significant improvements were presumed to be attributed to enhanced oxygen mass transfer and reduced charge transfer resistance arising from the CF-coated mesh substrate in the MEA.
