Wire-free electrochemical CO2 scrubbing

Anion-exchange membrane fuel cells offer the prospect of low-cost components thanks to their alkaline environment, yet they are plagued by carbonation of the electrolyte caused by the CO2 present in the feed air. Now, an electrochemical method for CO2 scrubbing using a membrane with mixed ionic-electronic conductivity offers a potential remedy.
