Description

Computer system capable of monitoring and controlling operation of fuel cell power generation system
Technical Field
The present invention relates to fuel cells, and more particularly to a computer system for monitoring and controlling the operation of a fuel cell power generation system.
Background
An electrochemical fuel cell is a device capable of converting hydrogen and an oxidant into electrical energy and reaction products. The inner core component of the device is a Membrane Electrode (MEA), which is composed of a proton exchange Membrane and two porous conductive materials sandwiched between two surfaces of the Membrane, such as carbon paper. The membrane contains a uniform and finely dispersed catalyst, such as a platinum metal catalyst, for initiating an electrochemical reaction at the interface between the membrane and the carbon paper. The electrons generated in the electrochemical reaction process can be led out by conductive objects at two sides of the membrane electrode through an external circuit to form a current loop.
At the anode end of the membrane electrode, fuel can permeate through a porous diffusion material (carbon paper) and undergo electrochemical reaction on the surface of a catalyst to lose electrons to form positive ions, and the positive ions can pass through a proton exchange membrane through migration to reach the cathode end at the other end of the membrane electrode. At the cathode end of the membrane electrode, a gas containing an oxidant (e.g., oxygen), such as air, forms negative ions by permeating through a porous diffusion material (carbon paper) and electrochemically reacting on the surface of the catalyst to give electrons. The anions formed at the cathode end react with the positive ions transferred from the anode end to form reaction products.
In a pem fuel cell using hydrogen as the fuel and oxygen-containing air as the oxidant (or pure oxygen as the oxidant), the catalytic electrochemical reaction of the fuel hydrogen in the anode region produces hydrogen cations (or protons). The proton exchange membrane assists the migration of positive hydrogen ions from the anode region to the cathode region. In addition, the proton exchange membrane separates the hydrogen-containing fuel gas stream from the oxygen-containing gas stream so that they do not mix with each other to cause explosive reactions.
In the cathode region, oxygen gains electrons on the catalyst surface, forming negative ions, which react with the hydrogen positive ions transported from the anode region to produce water as a reaction product. In a proton exchange membrane fuel cell using hydrogen, air (oxygen), the anode reaction and the cathode reaction can be expressed by the following equations:
and (3) anode reaction:
and (3) cathode reaction:
in a typical pem fuel cell, a Membrane Electrode (MEA) is generally placed between two conductive plates, and the surface of each guide plate in contact with the MEA is die-cast, stamped, or mechanically milled to form at least one or more channels. The flow guide polar plates can be polar plates made of metal materials or polar plates made of graphite materials. The fluid pore channels and the diversion trenches on the diversion polar plates respectively guide the fuel and the oxidant into the anode area and the cathode area on two sides of the membrane electrode. In the structure of a single proton exchange membrane fuel cell, only one membrane electrode is present, and a guide plate of anode fuel and a guide plate of cathode oxidant are respectively arranged on two sides of the membrane electrode. The guide plates are used as current collector plates and mechanical supports at two sides of the membrane electrode, and the guide grooves on the guide plates are also used as channels for fuel and oxidant to enter the surfaces of the anode and the cathode and as channels for taking away water generated in the operation process of the fuel cell.
In order to increase the total power of the whole proton exchange membrane fuel cell, two or more single cells can be connected in series to form a battery pack in a straight-stacked manner or connected in a flat-laid manner to form a battery pack. In the direct-stacking and serial-type battery pack, two surfaces of one polar plate can be provided with flow guide grooves, wherein one surface can be used as an anode flow guide surface of one membrane electrode, and the other surface can be used as a cathode flow guide surface of another adjacent membrane electrode, and the polar plate is called a bipolar plate. A series of cells are connected together in a manner to form a battery pack. The battery pack is generally fastened together into one body by a front end plate, a rear end plate and a tie rod.
A typical battery pack generally includes: (1) the fuel (such as hydrogen, methanol or hydrogen-rich gas obtained by reforming methanol, natural gas and gasoline) and the oxidant (mainly oxygen or air) are uniformly distributed in the diversion trenches of the anode surface and the cathode surface; (2) the inlet and outlet of cooling fluid (such as water) and the flow guide channel uniformly distribute the cooling fluid into the cooling channels in each battery pack, and the heat generated by the electrochemical exothermic reaction of hydrogen and oxygen in the fuel cell is absorbed and taken out of the battery pack for heat dissipation; (3) the outlets of the fuel gas and the oxidant gas and the corresponding flow guide channels can carry out liquid and vapor water generated in the fuel cell when the fuel gas and the oxidant gas are discharged. Typically, all fuel, oxidant, and cooling fluid inlets and outlets are provided in one or both end plates of the fuel cell stack.
The proton exchange membrane fuel cell can be used as a power system of vehicles such as vehicles and ships, and can also be used as a mobile or fixed power station.

The above fuel cell power generation system follows the following principles and principles:
a. the allowable magnitude of power output from the fuel cell stack 1 is related to the magnitude of the fuel cell operating temperature sensor 18, and generally, a relationship between the allowable magnitude of power output and the value of the sensor 18 can be found, and the closer the value of the sensor 18 is to the rated operating temperature, the greater or closer the allowable output power is to the rated output power (see fig. 2);
b. the matching relation of the power output by the fuel cell stack 1, the hydrogen flow and the air flow of the fuel supplied to the fuel cell is calculated according to the hydrogen metering ratio 1.2 and the air metering ratio 2.0;
c. the hydrogen relative humidity sensor 14 and the air relative humidity sensor 16 are respectively related to the flow rate of hydrogen and air, the temperature sensors 15 and 17 and the pressure of hydrogen and air (fig. 3), and generally the gas flow rate can be found, and a certain relative humidity relation curve is achieved under certain pressure and temperature conditions, generally, the higher the gas flow rate is, the higher the temperature is, the lower the pressure is, and the more difficult the gas high relative humidity value is to be achieved; conversely, the lower the gas flow, the lower the temperature, and the higher the pressure, the easier it is for the gas to reach high relative humidity values (see FIG. 3).
d. The faster the rotary humidifier rotates, the higher the temperature and relative humidity of the hydrogen or air entering the fuel cell.
According to theprinciple or principle of the operation of the fuel cell power generation system, the fuel cell power generation system controller is adopted, the rotating speed setting control of the rotating motor of the rotary humidifier is determined by monitoring and calculating the working temperature and the output power requirement of the fuel cell and the values of the sensor 14, the sensor 16, the sensor 15, the sensor 17 and the sensor 18, and the control of the hydrogen flow and the air flow is determined at the same time, so that the fuel cell stack can realize the following functions under any power output requirement: 1. the output power is controlled in relation to the working temperature; 2. the output power, the hydrogen flow and the air flow are controlled in a correlation manner, wherein the hydrogen flow and the air flow are respectively controlled to be 1.2 and 2.0 according to the metering ratio required by the output power so as to realize the control of the rotating speed of a hydrogen circulating pump motor and the rotating speed of an air pump motor; 3. the hydrogen flow and the air flow are respectively in parallel dynamic control with the motor speed in a corresponding humidifying device which can realize dynamic humidifying regulation control, so that the hydrogen and the air at any flow entering the fuel cell stack keep the optimal relative humidity (a certain value between 70% and 95%); 4. and adjusting and controlling the method according to the conditions of the outside weather temperature and the outside weather humidity as in the point 3, and achieving the same purpose as the point 3. The final purpose is to make the fuel cell stack realize high-efficiency operation and operation under the optimal working condition under the working condition of any power output requirement, and the fuel cell stack not only has the optimal fuel efficiency, but also can greatly prolong the service life.
The control subsystem in the overall fuel cell engine or overall power generation system is critical to achieving safe, efficient, and long-lived operation of the fuel cell engine or power generation system.
In the aspect of safety guarantee, when a control subsystem in a fuel cell engine or a power generation system detects certain working parameters, such as temperature, pressure, humidity, current and voltage, an alarm can be given in time, and self-protection of the fuel cell engine is executed at the same time, such as load cut-off and fuel hydrogen supply cut-off.
On the other hand, when the fuel cell power generation system is used as a function of testing the performance of the fuel cell stack or diagnosing the operating conditions of the entire fuel cell power generation system, the control subsystem in the fuel cell power generation system must simultaneously monitor and display all operating parameters such as temperature, pressure, humidity, voltage, cell voltage, etc. In order to optimize the operating conditions of the fuel cell stack or the entire fuel cell power generation system, the subsystems of the entire power generation system must be able to correct any of the operating operations, such as temperature, pressure, humidity, current, voltage, at any time. A conventional fuel cell starting system control subsystem usually adopts an integrated controller to respectively connect a plurality of monitoring points and control points in the whole fuel cell power generation system, so as to realize monitoring and control, as shown in fig. 4.
The traditional centralized controller is respectively connected with a plurality of monitoring points and control points in the whole fuel cell power generation system to realize monitoring and control. The traditional centralized controller respectively connects a plurality of monitoring points and control points of the whole fuel cell power generation system to realize monitoring and control, and has the following defects:
1. because the physical quantity needing to be monitored and controlled in the fuel cell power generation system is too much (as shown in figure 1), and the point-to-point single connection of the single chip microcomputer of the integrated controller and the sensor is realized, the connecting wires are too many, and the wiring is too complex;
2. the general weak current or weak voltage signal carries out digital analog signal mode communication with integrated control ware singlechip between the integrated control ware in the fuel cell power generation system and the sensor, because the communication line is too many, too miscellaneous, hardly accomplishes anti-interference, takes place communication and control easily and makes mistakes.
3. Because each node needing to be monitored and controlled in the fuel cell power generation system is too many, the communication interface of a single chip microcomputer of the central integrated controller is required to be too many, and other data operation, storage and processing functions are too strong, so that the controller is difficult to manufacture or is too expensive.
4. The display panel connected with the controller singlechip is small in screen, and often cannot display a plurality of monitoring parameters at the same time and record a large amount of data.
5. In particular, when the fuel cell power generation system is used for testing the performance of the fuel cell stack or diagnosing the operation conditions of the fuel cell power generation system, the control subsystem in the fuel cell power generation system must simultaneously monitor all the operation parameters, such as temperature, pressure, humidity, current, voltage, cell voltage, etc., in order to optimize the operation conditions of the entire fuel cell power generation system, the control subsystem of the entire power generation system must be able to correct any one of the operation parameters, such as temperature, pressure, humidity, current, voltage, etc., and the single chip technology of the centralized controller must first stop the operation of the entire fuel cell power generation system, modify the single chip program, and then restart the operation.
6. The programming of the controller singlechip is complex and must be completed by professional personnel.
