Abstract: An electrochemical cell includes a working electrode and a counter electrode. The working electrode is configured to adsorb and desorb a recovery target gas from a mixed gas containing the recovery target gas by electrochemical reaction. The counter electrode is configured to exchange electrons with the working electrode. The working electrode has a volume porosity that is equal to or greater than a volume porosity of the counter electrode.

Abstract: An electrochemical cell includes a working electrode and a counter electrode. A voltage is applied between the working electrode and the counter electrode such that electrons are supplied from the counter electrode to the working electrode so as to capture a target species. An electrode film of at least one of the working electrode and the counter electrode has an active material, a conductive aid and a binder. At least a part of the active material is contained as an agglomerate in the electrode film, and the maximum diameter of the aggregate is less than or equal to 10 μm.

Abstract: A gas recovery system configured to recover a recovery target gas from a gas mixture includes electrochemical cells and a gas passage between the electrochemical cells. The electrochemical cell has a working electrode including an adsorbent, and a counter electrode configured to exchange electrons with the working electrode. Electron donation occurs from the counter electrode to the working electrode when a voltage is applied between the working electrode and the counter electrode, such that the adsorbent adsorbs the recovery target gas along with the electron donation. At least one of the working electrode or the counter electrode includes an electrode film. The electrode film includes regions, each of which having a size smaller than a size of the electrochemical cell, and a reducing part that reduces warpage of the electrode film is located adjacent to the regions.
