Description
Technical Field
The application relates to the technical field of fuel cells, in particular to an end plate for a galvanic pile, the galvanic pile and a method for improving the insulation resistance of the galvanic pile.
Background
The electric pile is a place where electrochemical reaction occurs, and is also a core part of a fuel cell power system, and is formed by stacking and combining a plurality of single cells in series. The bipolar plates and the membrane electrodes are alternately overlapped, sealing elements are embedded between the monomers, and the sealing elements are tightly pressed by the front end plate and the rear end plate and then fastened by screw bolts, thus forming the fuel cell stack.
At present, a fuel cell stack is mostly used on a fuel cell vehicle, and because the voltage of the fuel cell stack on the fuel cell vehicle generally needs high voltage of more than four hundred volts, in order to prevent personnel inside and outside the vehicle from electric shock, it is important to ensure the safety of drivers, passengers and the surrounding environment of the vehicle, and the fuel cell stack keeps high insulation resistance.
Disclosure of Invention
In order to improve the insulation resistance of a fuel cell stack, the inventors have conducted extensive studies and experiments on the components constituting the stack, and have found that, during the experiments, an end plate, which is one of the main components of the stack, mainly serves to fix the stack and distribute fluid, and in particular, a hydrogen gas inlet and outlet, an air inlet and a coolant inlet and outlet are provided on the end plate, which, when continuous water films are formed on the surfaces of the inlet and outlet, may cause a decrease in the insulation resistance of the stack, and have conceived of modifying the end plate to prevent the decrease in the insulation resistance of the stack due to the end plate, according to an aspect of the present application, there is provided an end plate for a stack.
The end plate for the galvanic pile comprises an end plate body, wherein a gas inlet and a gas outlet penetrating the end plate body are formed in the end plate body, at least one protruding portion and at least one recessed portion are arranged on the surface of the gas inlet and the surface of the gas outlet, and the protruding portions and the recessed portions are alternately distributed along the gas flowing direction of the gas inlet and the gas outlet.
Therefore, when the end plate is used on a galvanic pile, even if water vapor is gathered on the gas inlet and outlet of the end plate, the water vapor is preferentially gathered in the concave part and is not gathered on the convex part, so that a continuous water film is prevented from being formed on the gas inlet and outlet, and the galvanic pile can keep high insulation resistance.
In some embodiments, the boss is an annular boss coaxial with the gas inlet and outlet; and/or the concave part is an annular concave part coaxial with the gas inlet and outlet. Thus, the surface of the gas inlet and outlet can be prevented from forming a continuous water film in the gas flowing direction, thereby preventing the insulation resistance of the galvanic pile from being reduced.
In some embodiments, at least one of the protrusions and depressions is square or triangular in cross-section. Thus, the processing of the convex parts and the concave parts is facilitated, for example, the convex parts and the concave parts which are alternately distributed along the gas flowing direction can be processed on the surface of the gas inlet and outlet in a tapping mode; moreover, the adoption of the processing mode is convenient for ensuring that the convex part and the concave part have smaller processing tolerance.
In some embodiments, the diameter of the gas port increases from the outside to the inside of the end plate body. To facilitate connection of external interfaces.
In some embodiments, the surface of the gas inlet and outlet is inclined at an angle in the range of 10 deg. + -5 deg.. Therefore, the smoothness of the gas flowing through the gas inlet and outlet can be ensured.
In some embodiments, a hard anodized layer is provided on a surface of at least one of the gas inlet/outlet, the raised portion, and the recessed portion. Thus, the corrosion resistance, wear resistance, weather resistance, insulation, adsorptivity, and the like of the gas inlet/outlet, the convex portion, and the concave portion provided with the hard anodized layer can be improved.
In some embodiments, the thickness of the hard anodized layer has a value in the range of 50 μm.+ -.10 μm. Therefore, the wear resistance and the insulativity of the gas inlet and outlet, the convex part and the concave part which are provided with the hard anodic oxidation layer can be ensured; the problems of low microhardness, high surface roughness and the like caused by the large thickness of the hard anodic oxidation layer can be avoided.
In some embodiments, the height of the protrusions and/or depth of the depressions range from 30mm±10mm. The inventors have found that by setting the height of the protruding portion and the height value of the recessed portion in appropriate ranges, not only can water accumulated on the surface of the gas inlet and outlet be prevented from forming a continuous water film in the gas flow direction, but also the problem that the water accumulated in the recessed portion cannot be brought to the outside of the end plate when gas flows out from the end plate due to the too high height of the protruding portion or the too deep depth of the recessed portion can be avoided.
In some embodiments, an insulating coating is provided on a surface of at least one of the gas inlet and outlet, the boss and the recess. Thus, the insulation performance of the end plate can be improved, and the insulation resistance of the electric pile can be further improved.
According to another aspect of the present application, a galvanic pile is provided.
The stack comprises the end plates for the stack described above. Therefore, even if water vapor gathers on the gas inlet and outlet of the end plate, the water vapor gathers in the concave part preferentially and does not gather on the convex part, thereby avoiding forming a continuous water film on the gas inlet and outlet and ensuring that the electric pile can keep higher insulation resistance.
According to yet another aspect of the present application, a method of increasing insulation resistance of a stack is provided.
The method for improving the insulation resistance of the electric pile comprises the step of using the end plate in the electric pile. Therefore, even if water vapor gathers on the gas inlet and outlet of the end plate, the water vapor gathers in the concave part preferentially and does not gather on the convex part, thereby avoiding forming a continuous water film on the gas inlet and outlet and ensuring that the electric pile can keep higher insulation resistance.
In some embodiments, further comprising introducing a drying gas into the encapsulation structure of the stack. Thus, the insulation resistance of the entire stack can be improved by the dry gas.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 to 4 schematically show an end plate for a galvanic pile according to an embodiment of the application.
As shown in fig. 3 and 4, the end plate for a galvanic pile includes an end plate body 20, a gas inlet and outlet 21 penetrating from an outer side 201 of the end plate body 20 to an inner side 202 of the end plate body 20 is integrally formed or machined on the end plate body 20, at least one protrusion 22 and at least one recess 23 are integrally formed, machined or connected to a surface of the gas inlet and outlet 21, and the protrusion 22 and the recess 23 are alternately arranged along a gas flow direction X of the gas inlet and outlet 21.
When the end plate is used on a pile, even if water vapor is gathered on the gas inlet and outlet 21 of the end plate, the water vapor is preferentially gathered in the concave part 23 and is not gathered on the convex part 22, so that a continuous water film is prevented from being formed on the gas inlet and outlet 21, and the pile can maintain high insulation resistance.
As one preferred embodiment of the gas inlet and outlet 21, as shown in fig. 3 and 4, the diameter of the gas inlet and outlet 21 decreases from the outer side 201 to the inner side 202 of the end plate body 20 to prevent water accumulated on the surface of the gas inlet and outlet 21 from flowing into the inner region of the stack under the action of its own gravity to ensure the dryness of the inner region of the stack, thereby ensuring a high insulation resistance of the stack. The gas inlet/outlet 21 is illustratively tapered in shape, and may be of a centrally symmetrical or an asymmetrically centrally symmetrical configuration. Specifically, the surface of the gas inlet/outlet 21 is inclined at an angle M (the inclined angle means the angle between the surface of the gas inlet/outlet 21 and the gas flow direction X) in the range of 10 ° ± 5 °, so as to ensure the smoothness of the gas flowing through the gas inlet/outlet 21 while avoiding the water accumulated on the surface of the gas inlet/outlet 21 from flowing into the inner region of the stack under the action of its own gravity.
As one of preferred embodiments of the boss 22, the boss 22 is an annular boss coaxial with the gas inlet and outlet 21 to avoid the surface of the gas inlet and outlet 21 from forming a continuous water film in the gas flow direction X, thereby avoiding a decrease in insulation resistance of the cell stack.
Preferably, the cross section of the boss 22 is square or triangular (as shown in fig. 3 and 4) so as to facilitate the processing of the boss 22, for example, the boss 22 distributed along the gas flow direction X may be processed on the surface of the gas inlet/outlet 21 by tapping; moreover, the machining described above also facilitates ensuring that boss 22 has relatively small machining tolerances.
Preferably, as shown in fig. 3 and 4, the height H1 of the boss 22 has a value ranging from 30mm±10mm, so as to avoid the problem that water accumulated in the recess 23 cannot be brought to the outside of the end plate when the gas flows out of the end plate due to the height of the boss 22 while avoiding the formation of a continuous water film in the gas flow direction by the water accumulated on the surface of the gas inlet/outlet 21.
As one of preferred embodiments of the recess 23, the recess 23 is an annular recess coaxial with the gas inlet and outlet 21. Thereby, it is possible to avoid the surface of the gas inlet/outlet 21 from forming a continuous water film in the gas flow direction X, thereby avoiding a decrease in insulation resistance of the stack.
Preferably, the cross section of the recess 23 is square or triangular (as shown in fig. 3 and 4), so that the recess 23 can be machined, for example, by tapping, the recess 23 distributed along the gas flow direction X can be machined on the surface of the gas inlet/outlet 21; moreover, the machining method is convenient for ensuring that the concave part 23 has small machining tolerance.
Preferably, as shown in fig. 3 and 4, the depth H2 of the recess 23 has a value ranging from 30mm±10mm, so as to avoid the problem that water accumulated in the recess 23 cannot be brought to the outside of the end plate when the gas flows out of the end plate due to the depth of the recess 23 being too deep while avoiding the formation of a continuous water film of water accumulated on the surface of the gas inlet and outlet 21 in the gas flow direction.
In some preferred embodiments, at least one of the gas inlet and outlet 21, the protruding portion 22 and the recessed portion 23 is coated with an insulating coating, for example, an epoxy coating, on the surface thereof to improve the insulating property of the end plate and thus the insulation resistance of the stack.
Preferably, the surface of at least one of the gas inlet and outlet 21, the protruding portion 22 and the recessed portion 23 is provided with a hard anodic oxide layer, that is, aluminum or an aluminum alloy is anodized to form a hard anodic oxide layer with high corrosion resistance, wear resistance, weather resistance, insulation and adsorptivity on the surface, and the method for preparing the hard anodic oxide layer may be, for example, sulfuric acid hard anodic oxide method, oxalic acid hard anodic oxide method or mixed acid hard anodic oxide method commonly used in the prior art, so as to ensure uniformity of thickness of the hard anodic oxide layer prepared on the surfaces of the gas inlet and outlet 21, the protruding portion 22 and the recessed portion 23, thereby ensuring stability of performance of the prepared hard anodic oxide layer. Further, the thickness of the hard anodic oxide layer is 50 mu m plus or minus 10 mu m, so that the wear resistance and the insulativity of the gas inlet and outlet, the convex part and the concave part provided with the hard anodic oxide layer are ensured; the problems of low microhardness, high surface roughness and the like caused by the large thickness of the hard anodic oxidation layer can be avoided.
Fig. 5 to 7 schematically show a galvanic pile 30 according to an embodiment of the application.
As shown in fig. 5 to 7, the stack 30 includes the aforementioned end plate for the stack 30, which is provided at an end of the stack 30, and the end plate body 20 of which is integrally formed or machined with a gas inlet and outlet 21 and a circulating water inlet 24, wherein the gas inlet and outlet 21 is mainly used for supplying air and hydrogen into the stack 30 and discharging the outside from the stack 30, and specifically, the gas inlet and outlet 21 includes an air inlet 211 for supplying air into the stack 30, an air outlet 212 for supplying air out of the stack 30, a hydrogen inlet 213 for supplying hydrogen into the stack 30, and a hydrogen outlet 214 for supplying hydrogen out of the stack 30. Thus, even if moisture is collected on the gas inlet and outlet 21 of the end plate, it is preferentially collected in the concave portion 23 and not on the convex portion 22, thereby avoiding the formation of a continuous water film on the gas inlet and outlet 21, and enabling the stack to maintain a high insulation resistance.
In some preferred embodiments, as shown in fig. 7, the gas port 21 increases in diameter from the outside 201 to the inside 202 of the endplate body 20 to facilitate connection with an external interface. The gas inlet/outlet 21 is illustratively tapered in shape, and may be of a centrally symmetrical or an asymmetrically centrally symmetrical configuration. Specifically, the surface of the gas inlet/outlet 21 is inclined at an angle M (the inclined angle means the angle between the surface of the gas inlet/outlet 21 and the gas flow direction X) in the range of 10 ° ± 5 °, so as to ensure the smoothness of the gas flowing through the gas inlet/outlet 21.
According to yet another aspect of the present application, a method of increasing insulation resistance of a stack is provided.
The method for improving the insulation resistance of the electric pile comprises the step of using the end plate in the electric pile. Thus, even if moisture is collected on the gas inlet and outlet 21 of the end plate, it is preferentially collected in the concave portion 23 and not on the convex portion 22, thereby avoiding the formation of a continuous water film on the gas inlet and outlet 21, and enabling the stack to maintain a high insulation resistance.
In some preferred embodiments, the method further comprises the step of introducing a dry gas into the packaging structure of the electric pile so as to improve the insulation resistance of the whole electric pile through the dry gas.
In the present application, the connection or installation is a fixed connection without special emphasis. The fixed connection may be implemented as a detachable connection or as a non-detachable connection as is commonly used in the art. The detachable connection may be implemented in the prior art, for example, by screwing or keying. The non-detachable connection may also be achieved using prior art techniques, such as welding or gluing.
What has been described above is merely some embodiments of the present application. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the application.
