Abstract: A fuel cell system (10) of the present invention has a fuel cell (20) which generates electric power by being supplied with reactive gas, an air compressor (C1) which supplies oxidizing gas to the fuel cell (20), a pressure sensor (P2) which detects the pressure of oxidizing gas, a pressure control valve (C2) which adjusts the pressure of oxidizing gas, and a control device (50) which adjusts the valve opening of the pressure control valve (C2) on the basis of the pressure detected by the pressure sensor (P2). When an abnormality in the pressure sensor (P2) is detected, the control device (50) opens the pressure control valve (C2) so that the valve opening thereof is equal to or larger than a predetermined opening. This arrangement ensures that the cell operation can be continued for a while instead of being immediately stopped in the event of abnormality in the pressure sensor (P2).

Abstract: Described is an electronic device and an electronic device control method. If voltage generated by the fuel cell, acquired from the voltage detection part, is greater than a specified voltage reference value (VRV), a display part displays the fuel cell as normal. However, if the generated voltage is smaller than the VRV, the residual fuel amount (RFA) detection part detects the RFA. If the RFA is smaller than a specified fuel reference value (FRV), the display part displays that the fuel is insufficient. However, if the RFA is greater than the FRV, the oxidizing agent concentration (OAC) detection part detects the OAC of the fuel cell. If the OAC is smaller than a specified OAC reference value, the display part displays that the oxidizing agent is insufficient. However, if the OAC is greater than the OAC reference value, the display part displays that the fuel cell is abnormal.
