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.
