Abstract: An electrochemical cell includes a working electrode, a counter electrode, and an electrolyte covering the working electrode and the counter electrode. The working electrode and the counter electrode are configured so that, in response to a voltage applied between the working electrode and the counter electrode, electrons are supplied from the counter electrode to the working electrode, and the working electrode adsorbs CO2 in association with the electrons being supplied. The counter electrode is not provided with an active material and is made of a porous material.

Abstract: A carbon dioxide recovery system is configured to separate carbon dioxide from gas containing the carbon dioxide via an electrochemical reaction and includes an electrochemical cell including a working electrode and a counter electrode. The working electrode includes a CO2 adsorbent. The CO2 adsorbent is configured to, when a first voltage is applied between the working electrode and the counter electrode, take in electrons flowing from the counter electrode to the working electrode and adsorb the carbon dioxide by a Coulomb force of the electrons without bonding to the carbon dioxide by sharing an electron orbital with the carbon dioxide. The CO2 adsorbent is configured to, when a second voltage different from the first voltage is applied between the working electrode and the counter electrode, discharge the electrons from the working electrode to the counter electrode and desorb the carbon dioxide.

Abstract: Provided is an electrochemical cell comprising a working electrode and a counter electrode. The working electrode comprises an electrode base material, a CO2 adsorbent, and a binder. Application of a voltage between the working electrode and the counter electrode causes electrons to be supplied from the counter electrode to the working electrode, and enables the CO2 adsorbent to bind to CO2 as electrons are supplied. The binder has electrical conductivity, and the CO2 adsorbent is held in the electrode base material by the binder.
