Problems solved by technology
[0006] However, in the case of a small-sized and long-life fuel cell used in portable electronic equipment, there is a problem that the state of the battery cannot be judged to be the fuel of the fuel cell (e.g., fuel such as methanol) only by detecting the output voltage of the battery. ) is not left, or the oxygen is insufficient, or the battery is abnormal

Embodiment Construction
[0057] First, the first embodiment will be described below.
[0058] FIG. 1 is a block diagram showing a configuration example of a camera 1 to which the present invention is applied.
[0059] The camera 1 is composed of an input unit 10 , a microcomputer 11 , a fuel cell 12 , a fuel remaining detection unit 13 , a voltage detection unit 14 , an oxidant concentration detection unit 15 , a water accumulation detection unit 16 , and a display unit 18 .
[0060] An operation is input by the user from the input unit 10 . The microcomputer 11 controls each part according to a user's instruction. In addition, the microcomputer 11 is internally equipped with memories such as ROM (Read Only Memory) and RAM (Random Access Memory), and appropriately stores necessary information.
[0061] The fuel cell 12 uses methanol as an example, generates energy from oxygen in the air, and supplies electric power of the camera 1 to necessary parts.
[0062] The remaining fuel amount detection uni...

The present invention relates to an electronic device and an electronic device operating control method in which the state of the fuel cell can be accurately determined. In cases where the voltage generated by the fuel cell 12 acquired from the voltage detection part 14 is greater than a specified voltage reference value V, the microcomputer 11 causes the display part 18 to display that the fuel cell 12 is normal, while in cases where this generated voltage is smaller than the voltage reference value V, the microcomputer 11 causes the residual fuel amount detection part 13 to detect the residual fuel amount. In cases where the residual fuel amount is smaller than a specified fuel reference value F, the microcomputer 11 causes the display part 18 to display that the fuel is insufficient, while in cases where the residual fuel amount is greater than the fuel reference value F, the microcomputer 11 causes the oxidizing agent concentration detection part 15 to detect the oxidizing agent concentration of the fuel cell 12. In cases where the oxidizing agent concentration is smaller than a specified oxidizing agent concentration reference value Z, the microcomputer 11 causes the display part 18 to display that the oxidizing agent is insufficient, while in cases where the oxidizing agent concentration is greater than the oxidizing agent concentration reference value Z, the microcomputer 11 causes the display part 18 to display that the fuel cell 12 is abnormal. The present invention can be applied to cameras.
Description
technical field [0001] The present invention relates to electronic equipment and an operation control method of the electronic equipment, in particular to the electronic equipment and the operation control method of the electronic equipment which can correctly judge the state of the fuel cell in the electronic equipment using the fuel cell as the power supply. Background technique [0002] Conventionally, portable electronic devices such as cameras have used lithium batteries or alkaline batteries as their power sources, but small fuel cells have been proposed as next-generation power sources. [0003] The fuel cell uses, as its fuel, oxygen in the air in addition to methanol. [0004] However, when a fuel cell is used as the power source of the camera, the usage time is limited by the amount of oxygen in the camera housing, so there is a problem that the camera cannot be used for a long time. [0005] On the other hand, in an electronic device using a lithium battery or an...
