1. A method of controlling an electrochemical reaction device,
the device comprising:
a first reactor having a first flow path, a second flow path, and a diaphragm, the first flow path defining a first room, the second flow path defining a second room, the diaphragm being provided between the first flow path and the second flow path;
a cathode facing on the first flow path; and
an anode facing on the second flow path;
the method comprising:
supplying a gas containing carbon dioxide to the first flow path and supplying an electrolytic solution to the second flow path;
reducing the carbon dioxide with the cathode to generate a reduction product; and
detecting a temperature of the physical exterior of the first reactor and adjusting a pressure in the first room in accordance with the detected temperature,
wherein the pressure in the first room is adjusted so that the pressure in the first room is increased in response to an increase of the detected temperature.
