Abstract
An electronic apparatus using a fuel cell as at least one electric power source. The fuel cell has an electric power output unit for outputting an electric power through a chemical reaction between fuel gas and oxidant gas, a purge device for purging the electric power output unit and a purge control unit for issuing a purge instruction to the purge device. The electronic apparatus has a monitor unit for monitoring a consumption power, an operation state or a manipulated state of the electronic apparatus, and a purge permission unit for judging from an output of the monitor unit whether the purge control unit is permitted to issue the purge instruction, and outputting a judgment result to the purge control unit.
Claims15
An electronic apparatus using, as at least one electric power source, a fuel cell having an electric power output unit for outputting an electric power through a chemical reaction between fuel gas and oxidant gas, a purge device for purging said electric power output unit and a purge control unit for issuing a purge instruction to said purge device, the electronic apparatus comprising:
- a monitor unit for monitoring a consumption power, an operation state or a manipulated state of the electronic apparatus;
- and
- a purge permission unit for judging from an output of said monitor unit whether said purge control unit is permitted to issue the purge instruction, and outputting a judgment result to said purge control unit.
A control method for an electronic apparatus using, as at least one electric power source, a fuel cell having an electric power output unit for outputting an electric power through a chemical reaction between fuel gas and oxidant gas, a purge device for purging said electric power output unit and a purge control unit for issuing a purge instruction to said purge device, the control method comprising steps of:
- monitoring a consumption power, an operation state or a manipulated state of the electronic apparatus;
- judging from a monitor result by said monitoring step whether said purge control unit is permitted to issue the purge instruction;
- and
- outputting a judgment result by said judging step to said purge control unit.
A fuel cell unit comprising:
- an electric power output unit for outputting an electric power through a chemical reaction between fuel gas and oxidant gas;
- a purge device for purging said electric power output unit;
- and
- a purge control unit for issuing a purge instruction to said purge device, in accordance with a permission signal from an electronic apparatus to be driven.
