The operation and effect of the fuel cell system of the structure of the present invention will be explained below:
when the control unit 70 outputs a drive timing command, the fuel compressor 22 of the fuel supply unit 20 is driven to supply the lng fuel from the fuel supply source 21 to the hydrogen generation unit represented by the reformer 25 through the fuel supply pipe 23, and hydrogen is generated while undergoing a series of processes such as de-yellowing, reforming, hydrogen conversion, and carbon monoxide removal. In response to a command from the controller, the reforming water supply valve 46 is opened, and water is supplied from the water supply source 41 to the reformer 25, converted into steam, and subjected to a reforming reaction.
According to the instruction from the control unit 70, the hydrogen gas is supplied to the fuel electrode 13 of the fuel cell reactor 10 through the fuel supply pipe 23, and the air compressor 32 is driven to supply the air to the air electrode 14 of the fuel cell reactor 10 through the air supply pipe 31. The humidification water supply valves 44a and 44b are opened, and water flows from the water supply source 41 into the humidifier 42, converts the fuel and air into vapor states, supplies the vapor states to the fuel electrode 13 and the air electrode 14, and generates electric power.
This is explained in more detail as follows: the fuel gas is supplied through the fuel supply pipe 23 and the fuel gas flow path Cf in the separators 15, 16; the air supply 30 is opened and air from the atmosphere is supplied through the air supply pipe 31 and the air flow path Co in the separators 15, 16.
The fuel gas flow path Cf and the air flow path Co of the separators 15 and 16 are supplied with fuel gas and air, and then come into contact with the fuel electrode 13 and the air electrode 14 to cause electrochemical reaction, thereby generating electric energy and heat energy.
That is, hydrogen ions H are generated at the fuel electrode 13+By electrochemical oxidation reaction of
The electrolyte membrane 12 transfers ions generated in the oxidation/reduction reaction, and the reduction reaction of air (oxygen) occurs at the air electrode 14
At this time, an electromotive force is generated between the fuel electrode 13 and the air electrode 14, and this electromotive force is output through the collectors 17 and 18 provided at both ends of the fuel cell reactor 10, and the current output from the collectors 17 and 18 is boosted to a normal voltage by the DC/DC converter of the electric power output unit, converted to a household ac power by the inverter, and supplied to the load.
At the same time, the load sensor 56 detects the load, transmits the information to the control unit 70, and the check terminal of the control unit 70, which receives the information, adjusts the supply amount of fuel and air, the humidification degree, the cooling degree of the fuel cell reactor 10, and the hydrogen gas supply degree in accordance with the current load amount, based on the degree of opening and closing, the rotational speed, and the compression degree of each of the adjusting devices, which are stored in advance in accordance with the load amount.
That is, as shown in fig. 3, after the system is driven, the flow meter 24, the carbon monoxide sensor 26, the first voltmeter 53, the second voltmeter 54, and the load sensor 56 provided at each location detect respective signals.
Next, the detected values of the signals received from the flow meter 24, the carbon monoxide sensor 26, the first voltmeter 53, the second voltmeter 54, and the load sensor 56 are compared with the set values of the signals set in advance in the check terminal of the control unit.
Meanwhile, whether the signal detection value exceeds the specified range of the signal set value is judged.
If the signal detection value does not exceed the specified range of the signal set value, the current driving state of the system is maintained; on the other hand, when the signal detection value is out of the predetermined range of the signal set value, the display unit notifies and displays a "warning" message, and at the same time, the system stops driving.
When the signal detection value does not exceed the predetermined range of the signal setting value, it is determined whether or not there is a difference between the signal detection value and the signal setting value, and if there is no difference, the fuel compressor 22, the air supply fans 27a, 27b, the air compressor 32, the humidification water supply valves 44a, 44b, the reforming water supply valve 46, the cooling water supply valve 82, the cooling water pump 84, the drain adjustment valve 86, and the purge exhaust valve 92 are maintained in the current state; if there is a difference, the control unit calculates the difference between the two signals, appropriately controls the various valves, compressors, and pumps, and returns to the stage where the flow meter 24, the carbon monoxide sensor 26, the first voltmeter 53, the second voltmeter 54, and the load sensor 56 provided at each part detect the respective signals.
