In a load disconnected state that the fuel cell is electrically disconnected from a load, the control method gradually opens the flow regulating valve that is configured to supply the oxidizing gas to a cathode of the fuel cell by a predetermined valve opening each time from a full-close position or gradually closes the flow regulating valve by a predetermined valve opening each time from a full-open position, so as to gradually change a supply amount of the oxidizing gas introduced to the cathode and cause hydrogen transmitted from an anode to the cathode in the fuel cell to be oxidized. The control method measures an open circuit voltage of the fuel cell accompanied with oxidation of the hydrogen and stores at least one valve-opening position among valve-opening positions of the flow regulating valve at a predetermined number of timings including a timing when the measured voltage shifts to an increase or shifts to a decrease, as a regulation reference valve-opening timing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control method of flow regulating valve of oxidizing gas and flow regulation device","description":"There is provided a control method of a flow regulating valve of an oxidizing gas in a fuel cell.
