Synergy for the plasma-based co2 conversion with the Solid Oxide Electrolysis Cell

The exploration of Mars needs in-situ resource utilization (ISRU) on Mars for life-maintaining, energy and food production [1].

Description
Summary:The exploration of Mars needs in-situ resource utilization (ISRU) on Mars for life-maintaining, energy and food production [1]. The Martian atmosphere is primarily co 2 (95.9%), Ar(1.9 %) and N 2 (1.9%). The abundantco 2 from the Mars atmosphere can be converted directly into O 2 and CO, which can be used for breathing and energy conversion respectively. Among all the co 2 conversion and oxygen production technologies, the most promising one is to combine the non-thermal plasmas and the solid oxide electrolyte cell (SOEC) with an oxygen separation membrane. Non-thermal plasma provides a highlychemical-activated environment to break the stable carbon-oxygen double bonds, and the SOEC can separate the o 2 w from the plasma environment for breathing, which also inhibits the backward reaction of CO combing with o 2 to form co 2 . The plasma-SOEC synergy effects have been reported by several researchers [2, 3] but no detailed investigations of the plasma-SOEC performance enhancement have been conducted. The principle behind it is still unclear.
