Description
Technical Field
The present invention relates to a fuel cell, and more particularly, to a fuel cell power generation system having an operation parameter monitoring function.
Background
A fuel cell is a device that can convert chemical energy generated when a fuel and an oxidant electrochemically react into electrical energy. The core component of the device is a Membrane Electrode (MEA), which consists of a proton exchange Membrane and two conductive porous diffusion materials (such as carbon paper) sandwiched between two surfaces of the Membrane, and finely dispersed catalysts (such as platinum) capable of initiating electrochemical reaction are uniformly distributed on the two side interfaces of the proton exchange Membrane contacting with the conductive materials. The electrons generated in the electrochemical reaction process are led out by conductive objects at two sides of the membrane electrode through an external circuit, thus forming a current loop.
At the anode end of the membrane electrode, fuel can permeate through a porous diffusion material (such as carbon paper) and perform electrochemical reaction on the surface of a catalyst, electrons are lost to form positive ions, and the positive ions can pass through a proton exchange membrane through migration to reach the other end of the membrane electrode, namely the cathode end. At the cathode end of the membrane electrode, a gas (e.g., air) containing an oxidant (e.g., oxygen) permeates through a porous diffusion material (e.g., carbon paper) and electrochemically reacts at the surface of the catalyst to give electrons that form negative ions that further combine with positive ions migrating from the anode end to form a reaction product.
In a proton exchange membrane fuel cell using hydrogen as fuel and air containing oxygen as oxidant (or pure oxygen as oxidant), the fuel hydrogen undergoes a catalytic electrochemical reaction in the anode region without electrons to form hydrogen positive ions (protons), and the electrochemical reaction equation is as follows:
the function of the proton exchange membrane in a fuel cell, in addition to serving to carry out the electrochemical reaction and to transport the protons produced in the exchange reaction, is to separate the gas flow containing the fuel hydrogen from the gas flow containing the oxidant (oxygen) so that they do not mix with each other and produce an explosive reaction.
In a typical pem fuel cell, the membrane electrode is generally placed between two conductive plates, and the two plates are both provided with channels, so the membrane electrode is also called as a current-guiding plate. The diversion grooves are arranged on the surface contacted with the membrane electrode and formed by die casting, stamping or mechanical milling and carving, and the number of the diversion grooves is more than one. The flow guide polar plate can be made of metal materials or graphite materials. The diversion trench on the diversion polar plate is used for respectively guiding fuel or oxidant into the anode region or the cathode region at two sides of the membrane electrode. In the structure of a single proton exchange membrane fuel cell, only one membrane electrode and two flow guide polar plates are arranged on two sides of the membrane electrode, one is used as the flow guide polar plate of anode fuel, and the other is used as the flow guide polar plate of cathode oxidant. The two flow guide polar plates are used as current collecting plates and mechanical supports at two sides of the membrane electrode. The diversion trench on the diversion polar plate is a channel for fuel or oxidant to enter the surface of the anode or the cathode, and is a water outlet channel for taking away water generated in the operation process of the battery.
In order to increase the power of the pem fuel cell, two or more single cells are connected together in a stacked or tiled manner to form a stack, or referred to as a cell stack. Such a battery pack is generally fastened together into one body by a front end plate, a rear end plate, and tie rods. In the battery pack, flow guide grooves, called bipolar plates, are arranged on both sides of a polar plate positioned between two proton exchange membranes. One side of the bipolar plate is used as an anode diversion surface of one membrane electrode, and the other side is used as a cathode diversion surface of the other adjacent membrane electrode. A typical battery pack also generally includes: 1) inlet and flow guide channels for fuel and oxidant gases. The fuel (such as hydrogen, methanol or hydrogen-rich gas obtained by reforming methanol, natural gas and gasoline) and oxidant (mainly oxygen or air) are uniformly distributed in the diversion trenches of the anode and cathode surfaces; 2) an inlet and an outlet for cooling fluid (such as water) and a flow guide channel. The cooling fluid is uniformly distributed in the cooling channels in each battery pack to absorb the reaction heat generated in the fuel cell and carry the reaction heat out of the battery pack for heat dissipation; 3) the outlets of the fuel and oxidant gases and the flow guide channel. The function of the device is to discharge the excessive fuel gas and oxidant which do not participate in the reaction, and simultaneously carry out the liquid or gaseous water generated by the reaction. The fuel inlet/outlet, the oxidant inlet/outlet, and the cooling fluid inlet/outlet are typically provided on one end plate or on both end plates of the fuel cell stack.
The proton exchange membrane fuel cell can be used as a power system of vehicles, ships and other vehicles and can also be manufactured into a movable or fixed power generation system.
A fuel cell power generation system generally consists of the following parts: the system comprises a fuel cell stack, a fuel hydrogen supply subsystem, an air supply subsystem, a cooling and heat dissipation subsystem, an automatic control subsystem and an electric energy output subsystem.
FIG. 1 shows a fuel cell power generation system in Shanghai Shenli technology, Inc., a fuel cell with a dynamic control device (patent application No. 200410016609.4, utility model No. 200420020471.0), in which a fuel cell engine monitor is used to dynamically control the operation of the fuel cell power generation system. The fuel cell power generation system comprises a fuel cell stack 1, a hydrogen cylinder 2, a pressure reducing valve 3, an air filter 4, an air compression supply device 5, a water-vapor separator 6, a water tank 7, a water pump 8, a radiator 9, a hydrogen circulating pump 10, a hydrogen path rotary type humidifier 11 capable of dynamically controlling humidification, an air path rotary type humidifier12 capable of dynamically controlling humidification, rotary type humidifier adjustable speed motors 13, 13', a hydrogen relative humidity sensor 14, a hydrogen temperature sensor 15 and a pressure sensor 19 on a hydrogen inlet pipeline, an air relative humidity sensor 16, an air temperature sensor 17 and a pressure sensor 20 on an air inlet pipeline, a cooling fluid temperature sensor 18 and a pressure sensor 21 on a cooling fluid inlet pipeline, a hydrogen temperature sensor 22 and a hydrogen pressure sensor 23 on a hydrogen outlet pipeline, a cooling fluid temperature sensor 24 and a cooling fluid pressure sensor 25 on a cooling fluid outlet pipeline, an air temperature sensor 26 and an air pressure sensor 27 on an air outlet pipeline, a fuel cell stack operating voltage and operating voltage monitor 28 of each single cell, a fuel cell stack operating current monitor 29, a load automatic cut-off switch 30, and a hydrogen automatic cut-off solenoid valve 31.
The above fuel cell power generation system follows the following principles and principles:
a. the allowable value of the output power of the fuel cell stack 1 is related to the rated operating temperature of the cooling fluid temperature sensor 18 on the cooling fluid inlet pipeline, and generally, a relation between the allowable power output value and the value of the sensor 18 can be found, wherein 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;
b. the matching relation of the output power of 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 hydrogen temperature sensor 15, the air temperature sensor 17 and the pressure of hydrogen and air, so that a relation curve of the gas flow to a certain relative humidity under a certain pressure and temperature condition can be found, and generally, the higher the gas flow is, the higher the temperature is, the lower the pressure is, and the more difficult the gas reaches a high relative humidity value; conversely, the lower the gas flow, the lower the temperature and the higher the pressure, the easier the gas reaches the high relative humidity value of the gas;
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 the principle or principle of the operation of the fuel cell power generation system, a fuel cell power generation system control subsystem is adopted, the rotation speed setting control of a rotating motor of a rotary humidifier is determined by monitoring and calculating the working temperature and the output power requirement of the fuel cell and the values of sensors 14, 15, 16, 17 and 18, and the control of hydrogen flow and air flow is determined at the same time, so that the fuel cell stack can realize the following functions under the condition of any power output requirement: 1. the output power is controlled in relation to the working temperature; 2. the correlation control of the output power, the hydrogen flow and the air flow (wherein the hydrogen flow and the air flow are respectively realized by controlling the rotating speed of a hydrogen circulating pump motor and the rotating speed of an air pump motor according to the metering ratios required by the output power, namely 1.2 and 2.0); 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, and the like. 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 readily available for modification of any one of temperature, pressure, humidity, current, voltage during operation.
At present, there are two main techniques for monitoring various operating parameters of a fuel cell power generation system: one is to monitor and control with a computer system when the fuel cell power generation system is used as a function for testing the performance of the fuel cell stack or when the operating conditions of the entire power generation system of the fuel cell are diagnosed. For example: the patent technology (chinese patent No. 200410017449.5) of shanghai myth technology company can monitor various operating parameters of a fuel cell power generation system, such as temperature, pressure, humidity, voltage of each single cell, and the like, and can directly control and correct one parameter of the operating conditions. The other is that when the fuel cell power generation system is used as a vehicle-mounted power system or as a movable power station, the monitoring and control are directly realized by a monitor.
The two technologies for monitoring various operating parameters of the fuel cell power generation system have the following defects:
1. a computer system is used to monitor various parameters of the fuel cell power generation system operation such as: although the temperature, pressure, humidity, voltage and voltage of each single cell in the fuel cell are intuitive, the computer system is often a heavy device, and when the fuel cell power generation system is used as a power system such as a vehicle-mounted power system or a ship-mounted power generation device or a power generation device which is moved frequently, the fuel cell power generation system is required to resist vibration, and the system is required to be simple and light, and the computer system cannot meet the requirements.
2. The operation of the fuel cell power generation system is directly monitored by a monitor for various operating parameters, such as: temperature, pressure, humidity, voltage, individual cell voltage in the fuel cell, have no direct visual perception. The fuel cell power generation system operation operator cannot intuitively judge whether the system is in a normal state at any time. The monitor usually alarms and shuts down when a certain parameter in the operation working parameters of the fuel cell power generation system reaches a dangerous limit. Thus, the operator is often unaware of the abnormal progress of the fuel cell power generation system and the opportunity for human intervention to adjust the operating parameters is lost.
