Abstract

A method of replacing a gas in a fuel cell system is provided, which comprises the steps of detecting that a fuel cartridge is connected to the fuel cell system having a fuel cell and supplying a fuel from the fuel cartridge on the basis of the detection to start replacement of gas in the fuel cell system. Thereby, a simple gas replacement method is provided for replacing the gas other than the fuel, which has entered the fuel cell system that is supplied with the fuel from the fuel cartridge, with the fuel. Especially, a user does not have to perform the gas replacement operation manually. The gas replacement can be automatically performed.

Claims

exact text as granted — not AI-modified
1 . A device for a fuel cell system, comprising:
 an attaching part for attaching a fuel cell system; and   a switch provided in the device,   wherein a fuel is supplied from a fuel cartridge connected to the fuel cell system in response to turn-on of the switch to start replacement of gas in the fuel cell system.   
     
     
         2 . The device according to  claim 1 , further comprising a control means, wherein the control means supplies the fuel from the fuel cartridge connected to the fuel cell system on the basis of the turn-on of the switch to starts the replacement of the gas in the fuel cell system. 
     
     
         3 . The device according to  claim 1 , wherein the fuel cell system comprises a control means, and the control means supplies the fuel from the fuel cartridge connected to the fuel cell system on the basis of the turn-on of the switch to start the replacement of the gas in the fuel cell system. 
     
     
         4 . The device according to  claim 1 , wherein the switch is a main switch of the device. 
     
     
         5 . The device according to  claim 1 , wherein the switch is a power source switch of the device. 
     
     
         6 . The device according to  claim 1 , wherein the switch is a switch other than a main switch of the device. 
     
     
         7 . The device according to  claim 1 , wherein the switch is a switch other than the power source switch of the device. 
     
     
         8 . A device for a fuel cell system, comprising:
 a fuel cell system comprising a fuel cell and a connecting part for connecting a fuel cartridge; and   a switch provided in the device,   wherein a fuel is supplied from the fuel cartridge connected to the fuel cell system in response to turn-on of the switch to start replacement of gas in the fuel cell system.   
     
     
         9 . The device according to  claim 8 , further comprising a control means, wherein the control means supplies the fuel from the fuel cartridge connected to the fuel cell system on the basis of the turn-on of the switch to start the replacement of the gas in the fuel cell system. 
     
     
         10 . The device according to  claim 8 , wherein the fuel cell system further comprises a control means, wherein the control means supplies the fuel from the fuel cartridge connected to the fuel cell system on the basis of the turn-on of the switch to start the replacement of the gas in the fuel cell system. 
     
     
         11 . The device according to  claim 8 , wherein the switch is a main switch of the device. 
     
     
         12 . The device according to  claim 8 , wherein the switch is a power source switch of the device. 
     
     
         13 . The device according to  claim 8 , wherein the switch is a switch other than a main switch of the device. 
     
     
         14 . The device according to  claim 8 , wherein the switch is a switch other than the power source switch of the device. 
     
     
         15 . A device for a fuel cell system, comprising:
 a fuel cell system comprising a fuel cell and a fuel tank; and   a switch provided in the device,   wherein a fuel is supplied from the fuel tank of the fuel cell system in response to turn-on of the switch to start replacement of gas in the fuel cell system.   
     
     
         16 . The device according to  claim 15 , further comprising a control means, wherein the control means supplies the fuel from the fuel tank of the fuel cell system on the basis of the turn-on of the switch to start the replacement of the gas in the fuel cell system. 
     
     
         17 . The device according to  claim 15 , wherein the fuel cell system further comprises a control means, wherein the control means supplies the fuel from the fuel tank of the fuel cell system on the basis of the turn-on of the switch to start the replacement of the gas in the fuel cell system. 
     
     
         18 . The device according to  claim 15 , wherein the switch is a main switch of the device. 
     
     
         19 . The device according to  claim 15 , wherein the switch is a power source switch of the device. 
     
     
         20 . The device according to  claim 15 , wherein the switch is a switch other than a main switch of the device. 
     
     
         21 . The device according to  claim 15 , wherein the switch is a switch other than the power source switch of the device.
