[0031] In order to solve the technical problem that a heating plate 3 is arranged inside the current collector plate 1 to provide heat for the fuel cell core for low-temperature cold start. However, after the fuel cell core is started, since the fuel cell core itself will dissipate heat and at the same time needs to dissipate heat, the residual heat on the heating plate 3 and the heating plate 3 is arranged in close contact with the inner wall of the inner cavity of the current collector plate 1, which will seriously affect the heat dissipation effect of the fuel cell core.

[0037] At both ends and on both sides of the top surface of the support plate 2, L-shaped corresponding grooves 23 are respectively arranged, and the upper openings of the L-shaped corresponding grooves 23 correspond to the lower openings of the L-shaped bottom grooves 13.

[0038] The first triangular telescopic frames 5 are respectively installed in the inner cavities of the L-shaped inner grooves 12, and the second triangular telescopic frames 6 are respectively installed in the inner cavities of the mounting bottom grooves 22. The first triangular telescopic frame 5 includes a triangular telescopic frame main body 51 and a sliding magnetic block 52 movably installed at the outer end of the output end of the triangular telescopic frame main body 51. The sliding magnetic block 52 is elastically installed on the small electromagnet 4 through a return spring 40, and T-shaped sliders 53 are respectively fixedly installed on the outer walls at both ends of the sliding magnetic block 52, and the T-shaped sliders 53 are respectively slidably arranged in the first T-shaped sliding grooves 121. The inner ends of the output ends of the triangular telescopic frame main body 51 are respectively movably installed on the inner wall of the inner cavity of the L-shaped inner groove 12. The connection mode of the second triangular telescopic frame 6 in the inner cavity of the mounting bottom groove 22 is the same as the connection mode of the first triangular telescopic frame 5 in the inner cavity of the L-shaped inner groove 12, and the composition and connection mode of each structure in the second triangular telescopic frame 6 are the same as the composition and connection mode of each structure in the first triangular telescopic frame 5.
[0039] The upper and lower ends of the connecting driving frame 7 are respectively slidably arranged in the L-shaped bottom groove 13 and the L-shaped corresponding groove 23. The connecting driving frame 7 includes an L-shaped magnetic suction frame 71 and an L-shaped driving frame 72 slidably installed in the inner cavity of the L-shaped corresponding groove 23. The L-shaped magnetic suction frame 71 is slidably arranged in the L-shaped bottom groove 13. The L-shaped magnetic suction frame 71 includes a magnetic sliding plate 711 and a bottom bump 712 fixedly installed on the outer bottom surface of the magnetic sliding plate 711.

The driving sliding plate 721 is fixedly installed on the outer end of the input end of the second triangular telescopic frame 6.
[0040] Specifically, when the fuel cell stack core needs to perform low-temperature cold start, the current collector plate 1 can be started. At this time, the heating plate 3 and the small electromagnet 4 can be started simultaneously. The small electromagnet 4 will generate magnetism, generating magnetic suction forces on the sliding magnetic block 52 and the magnetic sliding plate 711 respectively, so as to drive the two ends of the input end of the triangular telescopic frame body 51 to move relatively farther and farther apart. At this time, the output end of the triangular telescopic frame body 51 will be retracted into the L-shaped inner groove 12. And driven by the connecting driving frame 7, the two ends of the input end of the second triangular telescopic frame 6 can be driven to move relatively closer and closer, so that the whole second triangular telescopic frame 6 extends, pushing the heating plate 3 into the inner cavity of the current collector plate 1, so as to heat the stack core through the current collector plate 1. Similarly, when the small electromagnet 4 is powered off, under the elastic force of the return spring 40, the first triangular telescopic frame 5 can be driven to reset. At this time, the heating plate 3 will be pushed into the support plate 2, and the second triangular telescopic frame 6 resets. At this time, by separating the heating plate 3 from the current collector plate 1 and having a certain distance between them, while ensuring that the residual heat on the heating plate 3 will not be conducted to the stack core, the heat dissipation effect of the joint surface between the current collector plate 1 and the stack core can also be improved through the distance between the heating plate 3 and the current collector plate 1. The whole process is automatic, ensuring the cold start effect of the stack core while also improving the heat dissipation effect of the stack core.
[0041] Furthermore, when the current collector plate 1 and the support plate 2 are fixedly installed in a fitting manner, the insertion block 713 will be inserted into the insertion groove 723, so that the small electromagnet can drive the first triangular telescopic frame 5 and the second triangular telescopic frame 6 to move respectively through the connecting driving frame 7. The structure is ingeniously set. With the setting of one small electromagnet 4, multiple effects can be completed simultaneously, reducing the use and production costs.
[0042] In order to solve the technical problems of how to improve the heating effect of the heating plate 3 on the reactor core during low-temperature cold start of the reactor core and prevent the waste heat of the heating plate 3 from affecting the heat dissipation effect of the reactor core, as Figure 3 , Figure 4 , Figure 7 and Figure 8 shown, the following preferred technical solutions are provided:
[0043] A side wall groove 141 is provided on the outer inner wall at the upper end of the inner cavity of the communication hole 14, and a transverse communication hole 142 is provided on the outer inner wall of the inner cavity of the side wall groove 141. The outer end of the transverse communication hole 142 communicates with the L-shaped inner groove 12.
[0044] The blocking block 8 includes a blocking block main body 81 and a driving rod 82 fixedly installed on the outer middle wall of the blocking block main body 81. The outer ends of the driving rods 82 are respectively fixedly installed on the sliding magnetic blocks 52, and the blocking block main body 81 is slidably arranged in the side wall groove 141.
[0045] Specifically, when the small electromagnet 4 is not activated, the sliding magnetic block 52 on the first triangular telescopic frame 5 will move to the inner end of the first T-shaped sliding groove 121 under the elastic force of the return spring 40. At this time, under the transmission action of the driving rod 82, the blocking block main body 81 will block the communication hole 14, thereby reducing the influence of the waste heat of the heating plate 3 on the reactor core. When the small electromagnet 4 is activated, the sliding magnetic block 52 will drive the blocking block main body 81 to move from the communication hole 14 to the side wall groove 141 through the driving rod 82, so as to realize the communication of the communication hole 14. At this time, the heat transmission performance of the current collecting plate 1 can be improved, and the heating effect of the heating plate 3 can be improved. The whole process is automatic and convenient to use.
