GAS RECOVERY SYSTEM AND METHOD OF MANUFACTURING ELECTRODE FILM

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.
