摘要: In an electronic device, state detection elements are arranged at various locations of a fuel cell system supplies an electric power to a phone unit, the state detection elements detect states of the fuel cell system at the locations. A cell state detection unit detects an operating state of the fuel cell from an output signal of each of the state detection elements. A determination unit determines an operating mode to prompt action to be taken for the operating state of the fuel cell detected by the cell state detection unit. A content of the operating mode is displayed with an image of a character or a fictitious creature based on a determination by the determination unit.
