Embodiment 1

[0028] Such as Figure 1~5 As shown, this embodiment provides an injection molded blind end collector plate, including an injection molded plastic plate 1 and a metal collector plate 2. The metal current collecting plate 2 is installed in the fitting groove 11 so that the injection molded plastic plate 1 covers the back and the side of the metal current collecting plate 2, and the front of the metal current collecting plate 2 is exposed for contacting the stack core of the fuel cell. The edge of the metal collector plate 2 can be in a convex shape, which is snapped into the recess on the side wall of the fitting groove 11 to improve the connection strength.

[0029] Protruding pillars 12 are distributed on the bottom surface of the fitting groove 11, and grooves 21 corresponding to the position of the raised pillars 12 are distributed on the back of the metal current collecting plate 2. When the metal collecting plate 2 is installed in the fitting groove 11 , the protruding p...

Embodiment 2

[0032] Such as Figure 6 As shown, this embodiment provides a fuel cell, including the core 4, the end plate 5 and the injection-molded blind-end collector plate described in Embodiment 1. The injection-molded blind-end collector plate is fixed between the core 4 and the end plate 5 . With this structure, there is only an injection molded blind end collector plate between the end plate 5 and the core 4, which simplifies the assembly process; at the same time, the injection molded plastic plate 1 covers the back and side of the metal collector plate 2, which not only enhances the insulation effect, but also It can be used as a buffer engaging part connected with the end plate 5 to improve the accuracy and stability after assembly.

Abstract

The invention relates to an injection-molded blind-end collector plate and a fuel cell. The collector plate comprises an injection-molded plastic plate and a metal collector plate; the injection-molded plastic plate is provided with an embedding groove, the metal collector plate is installed in the embedding groove to enable the injection-molded plastic plate to cover the back surface and the side surface of the metal collector plate, the front surface of the metal collector plate is exposed, and the connector is used for connecting cores. Compared with the prior art, the traditional collector plates and insulating plates are integrated through an injection molding process, so that only the injection molding blind end collector plates are arranged between the end plates and the reactor core, and the assembly process is simplified; meanwhile, the injection molding plastic plate covers the back face and the side face of the metal collector plate, the insulation effect is enhanced, the injection molding plastic plate can serve as a buffering clamping piece, and the precision and stability after assembly are improved.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to an injection-molded blind-end collector plate and a fuel cell. Background technique [0002] A fuel cell is a power generation device that generates electricity through electrochemical reactions of hydrogen and oxygen. It has many advantages such as high energy conversion efficiency, environmental friendliness, and low noise. With the development and commercialization of fuel cell technology, the safety and durability of fuel cells have received more and more attention. Such as Figure 7 As shown, the conventional structure of a fuel cell includes a core 4, a current collecting plate 7, an insulating plate 6 and an end plate 5, and the current collecting plate, the insulating plate 6 and an end plate 5 are arranged in sequence at the blind end of the core 4, and this structure results in The production and assembly process is complicated, and it is easy to loosen during use, which affe...
