A. Then, when the stack unit 14 reaches the operating temperature, the fuel 5 U1 vaporized by the evaporation unit 12 is redirected to the reaction unit 13 via the control of the flow control unit 171, 172, 173, 174 instead of being activated to start combustion. The unit 151, 152 153 is configured to chemically react the fuel η in the reaction unit 13 to generate hydrogen gas, and thereafter, the fuel 1U that has generated hydrogen gas is input from the reaction unit 13 to the stack unit 14 to make the fuel U1 therein. The chemical energy is converted into electric energy (the electric power generation reaction, and finally, the fuel 111 that has undergone the electric power generation reaction is introduced into the post combustion unit 16 from the battery stack 10 to perform combustion to completely oxidize the fuel lu. When the fuel cell system 1 of the present embodiment is activated, the combustion fuel unit 151, 152, 153 is burned to generate heat energy to raise the temperature of the fuel cell system 1 to the operating temperature, thereby reducing the power supply of the fuel cell system 1. The power demand of the unit 20 is such that a smaller volume power supply unit can be disposed in the fuel 15 battery system 1 of the embodiment, thereby reducing the overall volume of the system and improving the system. Overall efficiency. U I: Referring to FIG. 4' is a schematic diagram of a fuel cell system according to another preferred embodiment of the present invention. To save space, only the difference between this embodiment and the previous embodiment will be described. In the example, the fuel cell system 2 includes a pump 21 connected to the π of the starting combustion unit itl51, 152, 153 to control the flow of the combustion-assisting gas into the combustion unit 151, 152, 153 without setting The flow control unit 171, 172, 173, m of an embodiment is a micro air pump, and the combustion gas system is air. 11 200826349 In addition, the evaporation unit 12, the reaction unit 13, and the stack unit of the present embodiment 14. The combustion unit bi, the 丨52, the 丨53, and the post-combustion unit 16 are set to be a third module 2 3. When the fuel cell system 2 is started, the fuel 1 丨丨 is heated by the evaporation unit 丄 2 5 After gasification, the fuel 111 is passed to the start-up combustion unit 1 5 1,152, 1 53 'at this time' if the flow control unit 22 controls the combustion-supporting gas 211 - and passes into the above-described start-up combustion unit 151, 152, 153, fuel 111 is in the start of the combustion unit The combustion reaction is carried out in 15 1,15 2,15 3 , after which the burned fuel η 1 is discharged through one of the bypass valve units 24 connected to the reaction unit 13 and the start combustion unit 151, 152, I". The at least one generated gas after the fuel U1·burning is not passed to the reaction unit 13, and the bypass valve unit 24 may be a three-way valve, a valve, a pumping pump, or a fan, etc., so that the gas after combustion can be directly In the present embodiment, the bypass valve unit 24 is a three-way valve. However, when the temperature of the fuel cell system 2 reaches the operating temperature, the flow rate control unit 22 controls the combustion-supporting gas 211 not to pass into the startup combustion unit 151, 152, 153, and causes the fuel cartridge to flow only through the startup combustion unit 151, 152, While burning, at this time, the bypass valve unit 24 is also cooperatively controlled to pass the fuel 111 into the reaction unit 13 so that the fuel 111 generates hydrogen gas in the reaction unit 13 for the subsequent generation of the electric generation reaction. 20 Therefore, it can be known from the above that the fuel cell system of the present invention firstly burns fuel into the start-up combustion unit to release heat, so that each unit adjacent to the start-up combustion unit can absorb heat energy to reach the work. The temperature 'reduces the need to start the power, and can reduce the power supply unit 12 200826349 and increase the fuel volume, thereby achieving the overall efficiency of the battery system to reduce the overall volume of the fuel cell system.
