The 2e ORR self breathing electrode is a two electron oxygen reduction cathode material independently developed by Epai Technology. The material uses carbon paper as the carrier, modified carbon material independently developed by Epai Technology as the catalyst, PTFE material as the hydrophobic agent, and is made through a narrow slit extrusion coating process. The production of low concentration hydrogen peroxide solution and high concentration hydrogen peroxide solution in discontinuous electrolysis processes can be achieved through different electrolytic cell designs.
