本文提出一种核潜艇电催化制氧耦合二氧化碳消除空气再生系统技术设想，该系统以膜电极构型电解反应器为核心，电解反应器中阳极进行水氧化反应制氧，阴极则将二氧化碳电催化还原为甲酸、甲醇等液体产物，实现核潜艇舱室供氧和二氧化碳消除一体化耦合。该系统只需常温常压条件下运行，运行过程中不产生氢气等危险气体副产物，产生的甲酸、甲醇等液体产物易于排放，能够联合集成二氧化碳吸收装置，且无需配套压缩机组。该设计能够改进和提高舱室空气再生系统使用性、安全性和潜艇隐蔽性，进一步提升核潜艇作战能力。
This paper proposes the technical concept of electrocatalytic oxygen production coupled with carbon dioxide elimination for air regeneration system in nuclear submarine. The system takes electrolysis reactor with membrane electrode configuration as the core. The electrolysis reactor performs water oxidation reaction to produce O2 on the anode and CO2 reduction into liquid products such as formic acid and methanol on the cathode, realizing the integrated coupling of O2 supply and CO2 elimination in the nuclear submarine cabin. The system only needs to operate under normal temperature and pressure conditions, and does not produce dangerous gas by-products such as H2 during operation. The liquid products such as formic acid and methanol are easily discharged. It can be integrated with a CO2 absorbtive device and does not require a compressor unit. This design can improve the usability, safety of air regeneration system and stealth performance, and further enhance the combat capability of nuclear submarine.
