The fuel cell's pile reactor core is piled up the assembly in proper order by a plurality of bipolar plate 2 and a plurality of membrane electrode 3 and forms, in order to guarantee the assembly precision, current pile reactor core is when the equipment, adopt reference column or visual detection to confirm the assembled position of piling up each bipolar plate 2 among the in-process usually, and reference column and visual detection are all controlled through bipolar plate 2's size appearance, because bipolar plate 2 can't guarantee each bipolar plate 2 complete coincidence because of dimensional tolerance's existence man-hour, the position of each bipolar plate 2's barycenter has the difference, thereby the pile reactor core is after the assembly is accomplished, the easy centre of mass skew that takes place of a plurality of bipolar plate 2 of pile reactor core, take place when the pile receives the exogenic action and warp easily, so that the unbalance becomes.
In view of the above, as shown in fig. 1, the present embodiment provides a reactor core, which includes a plurality of bipolar plates 2, a plurality of membrane electrodes 3, a first end plate 1 and a second end plate 4, wherein the first end plate 1 and the second end plate 4 are arranged at intervals along a first direction, the bipolar plates 2 and the membrane electrodes 3 are all located between the first end plate 1 and the second end plate 4, one membrane electrode 3 is arranged between any two adjacent bipolar plates 2, one bipolar plate 2 is arranged between any two adjacent membrane electrodes 3, and the mass centers of the bipolar plates 2 are located on the same straight line. The straight line where the centroids of the bipolar plates 2 are located is shown as L in fig. 1, and the deformation resistance of the stack can be significantly enhanced by arranging the centroids of the bipolar plates 2 on the same straight line.
In the present exemplary embodiment, the number of bipolar plates 2 is one greater than the number of membrane electrodes 3, i.e. the first end plate 1 and the second end plate 4 each bear directly against one bipolar plate 2.
As shown in fig. 2, when the first end plate 1 or the second end plate 4 receives an acting force of P, the reactor core provided in the prior art is deformed as shown by a solid line in the figure, and the reactor core provided in this embodiment is shown by a dotted line in the figure, because the centroid positions of the bipolar plates 2 are on the same straight line, the reactor core is not easily deformed and has high impact resistance and vibration resistance, a support rod or a support gasket for preventing the reactor core from being deformed can be eliminated, the number of parts is reduced, the overall weight is reduced, and the production cost can be reduced.
It should be noted that, as the length of the reactor core increases, the stability of the reactor core also inevitably decreases, but compared with the existing reactor core, under the condition of the same deformation requirement, the reactor core provided by the present embodiment can be arranged longer, so that the number of single cells in the reactor core can be significantly increased, and the power can be increased.

Although the centers of the bipolar plates 2 are positioned on the same straight line, the center of mass can only determine one point, and the degree of freedom of the bipolar plates 2 cannot be completely positioned, so that when the centers of mass of the two bipolar plates 2 are positioned on the same straight line and the positioning surfaces are parallel, the relative positions of the two bipolar plates 2 can be completely determined by using the positioning surfaces as another positioning reference. In the present embodiment, the bipolar plate 2 has a square structure, and the positioning surface may be one side surface of the bipolar plate 2.
The embodiment also provides a fuel cell, which comprises the fuel cell.
The present embodiment also provides a vehicle including the above fuel cell.
The present embodiment also provides a method for assembling a reactor core, which is used for assembling the above-described reactor core.
Specifically, as shown in fig. 3, the method for assembling the reactor core includes the steps of:
s100: the first end plate 1 is placed on the stacking platform.
The first end plate 1 can be manually placed on the stacking platform, or the first end plate 1 can be placed on the stacking platform by a manipulator. It will be appreciated that the stacking platform is provided with a locating structure for securing the first end plate 1 so as to stabilize the reactor core during stacking.
S200: a plurality of bipolar plates 2 and a plurality of membrane electrodes 3 are alternately stacked over the first end plate 1, and the centers of mass of the plurality of bipolar plates 2 are positioned on the same line in the process of alternately stacking the plurality of bipolar plates 2 and the plurality of membrane electrodes 3.
The balance performance of the reactor core and the deformation resistance can be ensured by keeping the mass centers of the bipolar plates 2 on the same straight line in the assembling process.
Specifically, in this embodiment, the number of the bipolar plates 2 is n +1, the number of the membrane electrodes 3 is n, n is a positive integer not less than 2, and the step S200 specifically includes the following steps:
s1: determining the centroid position of the first bipolar plate 2, and mounting the first bipolar plate 2 above the first end plate 1;
s2: mounting a first membrane electrode 3 over the first bipolar plate 2;
s3: determining the centroid position of the second bipolar plate 2, mounting the second bipolar plate 2 above the first membrane electrode 3, and the centroid position of the second bipolar plate 2 and the centroid position of the first bipolar plate 2 are located on the assembly line;
……
s2 n: mounting an nth membrane electrode 3 above an nth bipolar plate 2, wherein n is a positive integer not less than 2;
s2n + 1: the centroid position of the (n + 1) th bipolar plate 2 is determined, the (n + 1) th bipolar plate 2 is mounted above the (n) th membrane electrode 3, and the centroid position of the (n + 1) th bipolar plate 2 and the centroid position of the (n) th bipolar plate 2 are located on the assembly line.
In this embodiment, the bipolar plate 2 is measured by a centroid measuring device to determine the centroid position of the bipolar plate 2. After the centroid position of the bipolar plate 2 is determined, the bipolar plate 2 is grasped from the centroid measuring device by a manipulator, and the bipolar plate 2 is placed over the first end plate 1 or over the membrane electrode 3. The centroid measuring device is the prior art, and the detailed structure thereof is not repeated herein.
In this embodiment, the manipulator, the centroid measuring device, and the stacking platform are all located in the same coordinate system, the upper surface of the stacking platform is parallel to the horizontal plane, the assembly line is a straight line where the centroid of each bipolar plate 2 is located, and the assembly line is a straight line in the vertical direction in the assembly process and perpendicular to the first end plate 1.
After the centroid measuring device determines the centroid position of the bipolar plate 2, the current spatial coordinates of the centroid position of the bipolar plate 2 are first defined in the coordinate system, and after the manipulator grabs the bipolar plate 2 from the centroid measuring device, the spatial movement trajectory of the centroid position of the bipolar plate 2 can be determined according to the movement trajectory of the manipulator, and when the manipulator places the bipolar plate 2 on the first end plate 1 or the membrane electrode 3, the final position of the centroid position of the bipolar plate 2 can be determined.
When the robot carries the first bipolar plate 2 to the stacking platform by the centroid measuring device, the matching position of the first bipolar plate 2 and the first end plate 1 can be controlled by a vision system, for example, the first bipolar plate 2 and the first end plate 1 are both square, four sides of the first bipolar plate 2 are parallel to four sides of the first end plate 1, and the cathode inlet port of the first bipolar plate 2 and the cathode inlet port of the first end plate 1 coincide, so that the relative position of the first bipolar plate 2 and the first end plate 1 can be determined.
When the manipulator carries the second and the following bipolar plates 2 to the stacking platform by the mass center measuring device, the current mass center position of the bipolar plate 2 is coincided with the Z axis of the space coordinate of the mass center position of the previous bipolar plate 2 according to the mass center position of the previous bipolar plate 2 as a reference.
Alternatively, in steps S1-S2n +1, for step S2i +1, i is a positive integer equal to or greater than 1 and equal to or less than n;
when the (i + 1) th bipolar plate 2 is mounted above the (i) th membrane electrode 3 and the centroid position of the (i + 1) th bipolar plate 2 and the centroid position of the (i) th bipolar plate 2 are positioned on the assembly line, the (i + 1) th bipolar plate 2 is rotated around the assembly line so that the positioning surface of the (i + 1) th bipolar plate 2 is parallel to the positioning surface of the (i) th bipolar plate 2. Specifically, when the manipulator moves the i +1 th bipolar plate 2 to the position above the i-th membrane electrode 3, the i +1 th bipolar plate 2 and the i-th bipolar plate 2 are overlapped on the Z axis, and then whether the positioning surface of the i +1 th bipolar plate 2 is parallel to the positioning surface of the i-th bipolar plate 2 is judged according to the visual detection system, if not, the manipulator drives the i +1 th bipolar plate 2 to rotate by taking the assembly line as a central axis until the positioning surface of the i +1 th bipolar plate 2 is determined to be parallel to the positioning surface of the i-th bipolar plate 2 according to the visual detection system, and then the i +1 th bipolar plate 2 is placed above the i-th membrane electrode 3 along the vertical direction through the manipulator. In this way, the relative position of the two bipolar plates 2 in a straight line can be completely determined.
S300: the second end plate 4 is mounted to the uppermost bipolar plate 2.
The second end plate 4 may be manually placed on the uppermost bipolar plate 2, or the second end plate 4 may be placed on the uppermost bipolar plate 2 by a robot.
It should be noted that, since the mass of the membrane electrode 3 is smaller than that of the bipolar plate 2, the relative relationship between the mass center of the membrane electrode 3 and the mass center of the bipolar plate 2 is not limited during the stacking process, and the mass centers of the bipolar plate 2 and the membrane electrode 3 can be kept on the same straight line according to the requirement.
The method for assembling the reactor core of the electric reactor provided by the embodiment can ensure that the mass centers of the bipolar plates 2 of the assembled reactor core are positioned on the same straight line, can ensure the balance performance and the deformation resistance of the reactor core of the electric reactor, and can assemble more bipolar plates 2 and membrane electrodes 3 compared with the reactor core of the prior art under the condition that the requirement on the deformation degree is certain, thereby remarkably improving the power of the electric reactor.
