Abstract

The invention relates to a fuel cell metal bipolar plate inspection auxiliary structure and a fuel cell. The fuel cell metal bipolar plate inspection auxiliary structure comprises a voltage detection integrated quick plug part and a metal bipolar plate clamping part which are clamped with each other. On one hand, a first guiding structure and a second guiding structure are matched for guiding, and the connecting efficiency is improved; metal reeds are arranged to form pressing parts, and clamping force exists between the pressing parts and the metal reeds, so that poor contact is prevented, and the stability is improved; cantilever buckles on a plastic shell are fixed with protrusions, so that the connection stability of the voltage detection integrated quick plug part and the metal bipolar plate clamping part is guaranteed, and locking and taking down are convenient; moreover, shaking is avoided through the limiting effect of fin inserting grooves, the first guiding structure and the second guiding structure, fastening connection of the voltage detection integrated quick plug part and the metal bipolar plate clamping part is achieved, damage and deformation caused by repeated insertion are avoided, and the service life of polar plates is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and relates to a fuel cell testing device, in particular to a fuel cell metal bipolar plate inspection auxiliary structure and a fuel cell. Background technique [0002] In order to ensure the reliable operation of the fuel cell, it is necessary to monitor its voltage, so the auxiliary structure of the voltage inspection must be designed on the metal bipolar plate to realize the connection with the external wire interface, such as figure 1 As shown, the traditional method is to connect the wire of the external wire interface to the metal pin 91, and then insert the metal pin 91 into the hole-shaped voltage inspection auxiliary structure 92 on the metal bipolar plate, thereby realizing the external wire interface. Connected to the metal bipolar plate of the fuel cell, enabling voltage monitoring. [0003] However, this connection method is difficult to operate on a large stack, and there may b...
