Description
Technical Field
The present invention relates to a fuel cell, and more particularly, to a fuel cell that can respond quickly in the event of a sudden increase in output power.
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 ofthe 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, ships and other vehicles, and can also be used as a movable and fixed power generation device.
When the proton exchange membrane fuel cell can be used as a vehicle power system, a ship power system or a mobile and fixed power station, the proton exchange membrane fuel cell must comprise a cell stack, a fuel hydrogen supply system, an air supply subsystem, a cooling and heat dissipation subsystem, an automatic control part and an electric energy output part.
Fig. 1 is a fuel cell power generation system, in fig. 1, 1 is a fuel cell stack, 2 is a hydrogen storage bottle or other hydrogen storage device, 3 is a pressure reducing valve, 4 is an air filtering device, and 5 is an air compression supply device; 6', 6 are water-steam separators, 7 is a water tank, 8 is a cooling fluid circulating pump, 9 is a radiator, 10 is a hydrogen circulating pump, and 11, 12 are humidifying devices.
According to the principle or principle of the operation of the typical fuel cell power generation system, for example, the invention patent "a fuel cell with a dynamic control device" of shanghai mystery and technology ltd, chinese patent application No. 200410016609.4; 200420020471.0. the controller in the fuel cell power generation system monitors and calculates the working temperature and output power demand of the fuel cell, determines the control of hydrogen flow and air flow, and leads the fuel cell stack to realize under the condition of any power output requirement: 1. the output power is controlled in relation to the working temperature; 2. the output power is controlled in association with hydrogen flow and air flow, wherein the hydrogen flow and the air flow are controlled according to the required metering ratio of the output power, namely 1.2 and 2.0 respectively; 3. the hydrogen flow and the air flow are respectively linked and dynamically controlled with 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 percent and 95 percent); 4. and (4) 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 ultimate goal is to achieve high performance operation and optimal operating conditions for the fuel cell stack at any power output requirement, which can result in optimal fuel efficiency.
The principle and principle of the dynamic control of the fuel cell power generation system are that the automatic monitoring and calculation are carried out at different working temperatures, environments, power output requirements and the like according to the operation parameters of the fuel cell, and the control is carried out according to a set target value to achieve the operation of the fuel cell under the optimal working condition and high efficiency.
The output power is controlled in a correlation mode with hydrogen flow and air flow, and the hydrogen flow is metered by 1.2 according to the output power requirement; the air flow is controlled according to the output power required metering ratio of 2.0-2.5, otherwise, the whole efficiency of the whole fuel cell power generation system is reduced, the operation condition of the fuel cell is in an abnormal state after the fuel cell runs for a long timeunder the condition of hydrogen and air with overlarge flow, and the performance of the fuel cell is reduced or even irreversibly loses under severe conditions.
The dynamic target control of the fuel cell power generation system described above can ensure that the entire fuel cell is operated for a long period of time and can achieve a high efficiency state, but when the fuel cell power generation system is used as a power system in various vehicles or as a mobile or distributed power plant, a sudden increase in the required fuel cell output power occurs. For example, when a fuel cell electric vehicle starts, accelerates, or climbs a slope, or when a fuel cell power plant supplies power, a user suddenly increases some high-power load, and the like, all cause a situation that the output power of the fuel cell is required to suddenly increase.
The power generation principle of a fuel cell is actually that hydrogen fuel in the fuel cell is combined with oxygen in the supply air to the fuel cell to generate water, and this chemical reaction process is a process in which most of chemical energy is converted into electrical energy. The speed at which the fuel cell generates electricity is affected by many factors:
(1) the speed and sufficiency of supplying hydrogen fuel, air to the fuel cell;
(2) the diffusion rate of hydrogen, oxygen in air, to the electrodes in the fuel cell;
(3) the catalytic reaction speed of hydrogen and oxygen in the air in the electrode;
the (2) and (3) points are related to the design of the power generation capacity of the fuel cell.
Generally, when a sudden start, acceleration, or the like of a fuel cell electric vehicle occurs, or a sudden load is applied by a user supplied from a fuel cell power plant, or the like, the response speed of the output power of the fuel cell is required to be very fast.
The fuel cell power generation system designed at present has the following serious technical drawbacks:
although the design of the rated output power of the fuel cell, i.e. the power generation capacity of the fuel cell, will generally satisfy the requirement of the maximum power requirement of the vehicle-mounted power source or the power station, when the fuel cell is used as the vehicle-mounted power source or the power station, it is often happened that the fuel cell suddenly increases from the idle state or the small power requirement to the large power or even the maximum power requirement. The principle and principle of the dynamic control of the current fuel cell power generation system are to realize automatic monitoring and calculation according to the operation parameters of the fuel cell and different working temperatures, environments, power output requirements and the like, and to control according to a set target value to achieve the high-efficiency operation of the fuel cell under the optimal working condition. The output power is controlled in a correlation mode with hydrogen flow and air flow, and the hydrogen flow is metered by 1.2 according to the output power requirement; the air flow is controlled according to the output power requirement metering ratio of 2.0-2.5. The output power and the air flow are generally controlled in a correlation mode, according to the power requirement of an external circuit, the rotating speed of a motor of the air conveying device is calculated and adjusted to achieve the air flow adjustment, and the air flow is enabled to achieve the target control requirement of 2.0-2.5.
That is, when the output power of the fuel cell is suddenly increased by the external circuit, the fuel cell power generation system must first adjust the motor speed of the air delivery device in the fuel cell power generationsystem, such as the air compressor and the blower, so that the motor speed is greatly increased to increase the flow rate of the air delivered to the fuel cell stack and achieve the air flow rate requirement for increasing the output power.
Generally, motor speed regulation is time-consuming, and especially when the motor is regulated from low speed to high speed, a time interval of 0.5-1 second or even longer is often required. However, when the fuel cell electric vehicle is suddenly started, accelerated, or the like, or when a user supplied by a fuel cell power plant is suddenly loaded, or the like, the response speed of the output power of the fuel cell is required to be very fast, and the time interval is often much less than 0.5 second.
Therefore, the above situation may occur that the whole fuel cell power generation system cannot respond quickly to the power demand of sudden increase in output because the air is not delivered in time, and in severe cases, the whole fuel cell power generation system may be broken down.

On the other hand, when the motor speed regulation of the air compression device reaches the normal supply air flow and pressure, the normally closed electromagnetic valve can be automatically closed, and the supply air compression pump can start to store air again according to the pressure in the compressed air storage tank until the set pressure is reached, and the supply air compression pump automatically stops working. In addition, the compressed air in the compressed air storage tank can be used as the air source for vehicle pneumatic, such as pneumatic braking, pneumatic opening and closing of the vehicle door.
