Abstract

Room-temperature ionic liquids are utilized in a new CO2 capturing fuel cell. The cell is aimed at the efficient and cost effective removal of CO2 emitted from transportation related sources. The CO2 is captured from the atmosphere and is later converted into carbon free synthetic fuel such as methanol. In this study we optimized the operating conditions and the cell electrolytes. With ionic liquids such as 1-Butyl-1-methylpyrrolidinium dicyanamide, the extraction efficiencies increased to ∼20% while simultaneously making the capture process more robust. The ionic liquid approach is also compared to existing aqueous electrochemical CO2 concentration previously proposed by NASA for aerospace applications but with much lower efficiencies.
