Characteristics of Electrolytic Deoxygenation Devices Using SiC and SWCNT Electrodes

Abstract

Electrolytic deoxygenation devices have been fabricated using SiC, SWCNT, graphene, and PEDOT*PSS for the electrodes. Characteristics of devices were studied by measuring currents, O2 and H2 concentrations, and humidity during deoxygenation in a closed container. Performances of the devices being composed of cation or anion exchange membrane are discussed comparing with the standard catalyst of Pt-black. It is found that generation of moisture and H2 was substantially involved in the deoxygenation.

Evaluation limit of O2 permeability in barrier films by electrolytic oxygen pump

“…9 is the evaluation limit of OTR. The background current originates from water electrolysis, which occurs at 1.229 V, [20][21][22] electron emission from electrode material to electrolyte solution, and/or the other unknown factors. It is noted that the plateau of i ∞ observed at 0.7 < V app < 1.3 V shown in Fig.…”
