Abstract:
1. A gas generation device that generates a first gas and a second gas by electrolysis, comprising: an electrolyzer divided into a first chamber and a second chamber and containing therein an electrolytic bath including a compound to be electrolyzed; a first discharge path through which the first gas generated in said first chamber is discharged; a second discharge path through which the second gas generated in said second chamber is discharged; first and second adsorbers that each include an adsorbent for adsorbing a third gas mixed in the first gas; third and fourth adsorbers that each include an adsorbent for adsorbing the third gas mixed in the second gas; a connector configured to be switchable between a first state and a second state, the first state being the state where said first and third adsorbers are connected to said first and second discharge paths, respectively, and said second and fourth adsorbers are disconnected from said first and second discharge paths, respectively, the second state being the state where said second and fourth adsorbers are connected to said first and second discharge paths, respectively, and said first and third adsorbers are disconnected from said first and second discharge paths, respectively; a first heater that heats the adsorbents in said first and third adsorbers; a second heater that heats the adsorbents in said second and fourth adsorbers; and a controller that controls said connector, said first heater, and said second heater, wherein said controller switches said connector between said first state and said second state, and when said connector is in said first state, said controller controls said first and second heaters such that the third gas is adsorbed by the adsorbents in said first and third adsorbers and the third gas is desorbed from the adsorbents in said second and fourth adsorbers, and when said connector is in said second state, said controller controls said first and second heaters such that the third gas is adsorbed by the adsorbents in said second and fourth adsorbers and the third gas is desorbed from the adsorbents in said first and third adsorbers, the gas generation device further comprising: a first circulation path through which the third gas desorbed from the adsorbent in said second adsorber is guided to said first chamber when said connector is in said first state, and through which the third gas desorbed from the adsorbent in said first adsorber is guided to said first chamber when said connector is in said second state; and a second circulation path through which the third gas desorbed from the adsorbent in said fourth adsorber is guided to said second chamber when said connector is in said first state, and through which the third gas desorbed from the adsorbent in said third adsorber is guided to said second chamber when said connector is in said second state.
