Description
Technical Field
The present invention relates to the field of new energy automobiles, and more particularly, to an integrated hydrothermal heat dissipation system for a fuel cell system.
Background
Fuel cells, particularly hydrogen fuel cells, are considered as one of the future energy solutions because of their wide fuel sources, no pollution, and zero emissions. The hydrogen fuel cell (hereinafter referred to as "fuel cell") operates on the principle that chemical energy is converted into electric energy by chemically reacting hydrogen gas with oxygen gas. More specifically, the basic principle is that hydrogen is sent to an anode plate (negative electrode) of a fuel cell, one electron in hydrogen atoms is separated by the action of a catalyst (platinum), hydrogen ions (protons) losing the electron pass through a proton exchange membrane to reach a cathode plate (positive electrode) of the fuel cell, while electrons cannot pass through the proton exchange membrane, and the electrons can only reach the cathode plate of the fuel cell through an external circuit, so that current is generated in the external circuit. After reaching the cathode plate, the electrons are recombined with oxygen atoms and hydrogen ions into water. Since the oxygen supplied to the cathode plate is available from air, electrical energy can be continuously supplied as long as hydrogen is continuously supplied to the anode plate, air is supplied to the cathode plate, and water (vapor) is timely taken away. The electricity generated by the fuel cell is supplied to the motor through devices such as an inverter and a controller, and then drives the wheels to rotate through a transmission system, a drive axle and the like, so that the vehicle can run on the road.
In order to secure the insulating performance of a fuel cell stack (hereinafter referred to as a "stack"), the ion concentration of the coolant is highly required (deionized water is required). However, fuel cell auxiliary systems (including, for example, intercoolers, DC-DC converters, and air compressor controllers) do not have this requirement. The ion concentration of the coolant is required to be high, and the cost increases. The core of the fuel cell stack is that the membrane electrode and the ion exchange are carried out by the proton exchange membrane, and the optimal operation state temperature of the proton exchange membrane is between 70 and 90 ℃. Too low a temperature can lead to reduced catalytic activity of the platinum in the membrane electrode, while too high a temperature can lead to serious dehydration of the proton exchange membrane, which is unfavorable for proton conduction, so that maintaining proper temperature and humidity is of great importance. Under the working environment of the fuel cell below 0 ℃, water generated by the reaction on the cathode side is easy to freeze, so that a catalytic layer and a diffusion layer are blocked to prevent the reaction from proceeding, and the volume change generated by the water icing can damage the structure of the membrane electrode assembly. Therefore, the external output power of the fuel cell start-up is generally required to be carried out by enabling the internal temperature of the cell stack to reach more than 0 ℃.
The current fuel cell technology has the following technical problems:
1) The main technical scheme at present connects the fuel cell stack with an intercooler and a radiator in the fuel cell auxiliary system, and has the defects of large water circulation loop, more deionized water requirements and frequent replacement; and
2) The heat dissipation part of the current fuel cell system is divided into two parts in consideration of temperature difference (the working temperature of the cell stack is 70-90 ℃ and the temperature of the controller is 60-70 ℃), the main radiator is used for dissipating heat of the cell stack and the intercooler (a cooling loop of the cell stack), the auxiliary radiator is used for dissipating heat of the air compressor, the controller and the DC-DC (a cooling loop of the auxiliary system), and the heat dissipation system is complex and has low efficiency.

Detailed Description
The features of the present invention will become more apparent from the detailed description set forth below when taken in conjunction with the drawings.
Fig. 1 is an exemplary block diagram of a fuel cell system 100 integrated with a hydrothermal heat dissipation system according to one embodiment of the invention.
As shown in fig. 1, the fuel cell system 100 may include a fuel cell stack 102, a fuel cell auxiliary system (hereinafter referred to as "auxiliary system") 104, and a heat dissipation system. In this example, the heat dissipation system is a hydrothermal heat dissipation system. In order to dissipate heat from the stack 102 and the auxiliary system 104, the heat dissipation system may provide cooling to the stack and the auxiliary system, respectively, where stack cooling is used to ensure that the operating temperature of the fuel cell stack is within a reasonable range, and to ensure the reaction speed and system efficiency of the fuel cell, and auxiliary system cooling is used to ensure that the operating temperatures of the relevant components in the auxiliary system are within a reasonable range, so that the components may operate normally.
As one example, as shown in fig. 1, the stack cooling section in the fuel cell system 100 of the present invention includes a stack 102, a heat exchanger 106, and a first water pump 108, constituting a stack cooling circuit or an internal circulation circuit. The auxiliary system cooling section includes a heat exchanger 106, a radiator 110, an auxiliary system 104, a second water pump 114, and a three-way valve 116, forming an auxiliary system cooling circuit or an external circulation circuit. The auxiliary system 104 may further include, for example, an intercooler 118, a DC-DC converter 120, and an air compressor and controller 122.
It is noted that, as shown in fig. 1, the inner circulation loop and the outer circulation loop of the fuel cell system 100 of the present invention are connected to each other by a common heat exchanger 106 to realize heat exchange. The advantages of this structural design will become more apparent in the following detailed description of the operation of the fuel cell system of the present invention.
As one example, a fuel cell system may be divided into the following three phases from a cold start to operation in a suitable temperature range:
stage 1: cold start of a cell stack
During cold start of the fuel cell, the temperature of the fuel cell is lower, and the outer circulation loop can be used for raising the temperature of the inner circulation water path, so that the temperature rise of the interior of the cell stack is accelerated until the start of the cell stack is completed, for example, when the temperature of the cell stack reaches a starting temperature threshold.
To this end, in this example, the three-way valve 120 is configured to open the connection interface with the heat exchanger 106 while closing the bypass interface, the radiator 110 is deactivated, and the first water pump 108 and the second water pump 118 are activated. At this time, the heat emitted from the fuel cell stack itself is circulated by the first water pump 108 through the internal circulation loop, so that the internal temperature of the stack is uniform. Meanwhile, the water temperature in the outer circulation loop is increased by the emitted heat of the auxiliary system in the outer circulation loop, circulation is performed under the drive of the second water pump 118, heat transfer between the inner circulation loop and the outer circulation loop is achieved through the heat exchanger 106, and the heat is transferred to the inner circulation loop, so that the temperature of an inner circulation waterway is increased, the increase of the internal temperature of the cell stack is facilitated, and the cold starting time of the cell is shortened. In other words, at this stage, the inner and outer circulation circuits exchange heat through the heat exchanger, and the outer circulation circuit is configured to help the inner circulation circuit raise the temperature.
Stage 2: after the cell stack is started
When the fuel cell stack is successfully started, the heat emitted by the fuel cell stack begins to rise rapidly, and the external circulation loop is not required to be heated continuously, and meanwhile, the auxiliary system in the external circulation loop enters the optimal working temperature range of the fuel cell stack (as mentioned before, the optimal working temperature range of the fuel cell stack is about 70-90 ℃ and the optimal working temperature range of the auxiliary system is about 60-70 ℃) before the fuel cell stack enters the optimal working temperature range of the fuel cell stack, so that the auxiliary system needs to be cooled to maintain the operation of the fuel cell stack in the optimal working temperature range.
To this end, in this example, the three-way valve 120 opens the bypass interface and closes its connection interface with the heat exchanger 106, while the radiator 110 begins to operate. At this time, the fuel cell stack 102 continues to increase in temperature by self-heating after the start-up is successful until the temperature rises to the optimum operating temperature range. The auxiliary system 104 radiates heat from the components, such as the intercooler 112, through the radiator 110, and maintains the components to operate in an optimal operating temperature range. In other words, at this stage, the inner circulation circuit and the outer circulation circuit operate independently, cooling the stack and the auxiliary system, respectively.
Stage 3: the cell stack reaches the optimal operating temperature
When the fuel cell stack continues to increase in temperature until it reaches its optimal operating temperature range, the inner circulation loop alone cannot suppress its continued increase in temperature, and therefore it is necessary to rely on the outer circulation circuit to help it maintain temperature.
To this end, in this example, the three-way valve 120 reopens the connection interface with the heat exchanger 106, thereby removing a portion of the heat of the stack 102 through the heat exchanger 106, thereby maintaining the stack 102 in the optimal operating temperature range. In this operating state, the heat sink 110 simultaneously dissipates heat from the stack 102 and the auxiliary system 104. In other words, at this stage, the inner and outer circulation circuits exchange heat through the heat exchanger, and the outer circulation circuit is configured to help the inner circulation circuit reduce the temperature.
The above describes an example structure of the fuel cell cooling system of the invention. Compared with the prior art, firstly, the invention realizes that the optimal working temperature of the battery stack and the auxiliary system is maintained by using one radiator, simplifies the structure and improves the heat dissipation efficiency. The principle of achieving this effect is: the operation temperature of the auxiliary system is lower than the operation temperature of the cell stack, and a temperature difference exists between the auxiliary system and the cell stack; by utilizing the temperature difference, heat exchange and refrigeration can be effectively carried out on the cooling liquid (deionized water) of the cell stack, so that the optimal operation temperature of the cell stack is maintained.
Secondly, the invention realizes the acceleration of the cold start of the fuel cell, because the temperature of the cooling liquid (deionized water) of the cell stack is heated by using the heat dissipation energy of the auxiliary system operation, and the cell stack is heated after circulation, thereby achieving the acceleration of the cold start process.
Third, the present invention enables reduced deionized water (stack coolant) requirements. As described previously, only the water in the stack cooling circuit is required to be deionized water, so by the design of the present invention, the length of the stack cooling circuit is reduced, and so the need for deionized water is correspondingly reduced. Accordingly, because the length of the loop is reduced, parts in the loop are fewer, ion precipitation is reduced, the concentration of ions in a waterway is ensured, parasitic parts which possibly generate ions in the loop are reduced, the deionized water can be used for replacing a longer period, the insulating performance of a product is improved, and the cost is obviously reduced.
Fourth, the invention integrates the main heat dissipation of the battery stack and the auxiliary system heat dissipation through the heat exchanger and the three-way valve, so that the system integration level is higher, and meanwhile, the dependence of the system on external resources is reduced.
Fig. 2 is an exemplary structural diagram of an automobile 200 using a fuel cell system according to the present invention. As shown in fig. 2, an automobile 200 includes a fuel cell system, such as the fuel cell system 100 described in fig. 1 that integrates a hydrothermal heat dissipation system. It will be appreciated by those skilled in the art that although the present invention has been described by way of example in terms of a hydrogen fuel cell system, the fuel cell is not limited to a hydrogen fuel cell, and the present invention may be applied as long as the optimum operating temperature range of the fuel cell auxiliary system in the fuel cell system is lower than the optimum operating temperature range of the fuel cell stack. In addition, the invention is not only suitable for the automobile taking the fuel cell as the power, but also suitable for the hybrid electric automobile taking the fuel cell system as part of the power.
What has been described above includes examples of aspects of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Accordingly, the disclosed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims.
