Problems solved by technology

When this structure is matched with the sealing groove, the position is prone to lateral displacement, and this problem has not been solved, and even seldom studied
This will not only lead to the aforementioned sealing failure problem, but also cause the rupture of the polar plate, plastic deformation of the proton membrane frame, etc., seriously affecting the safe use of the fuel cell

Abstract

The invention discloses a sealing and positioning auxiliary structure for sealing and positioning a sealing groove and a sealing part. The sealing groove is formed in a polar plate, the sealing part is arranged in the sealing groove, a sealing part limiting part is formed on the surface of the sealing groove, and a reverse positioning part opposite to the sealing part limiting part is formed on the surface of the sealing part. The reverse positioning part of the sealing part and the sealing part limiting part of the sealing groove are assembled in a matched mode, and a reference is provided for the assembling position of the sealing part. And the sealing element limiting part of the sealing groove prevents the sealing part from laterally deviating in the assembling process to influence thesealing effect.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a sealing and positioning auxiliary structure for sealing and positioning a sealing groove and a sealing component, and particularly relates to its mechanical connection structure. Background technique [0002] The essence of a fuel cell is to generate electricity through the electrochemical reaction of hydrogen and oxygen, among which hydrogen and oxygen are essential reaction raw materials for fuel cells. The two gases enter the interior of the fuel cell for a precise chemical reaction, and it is necessary to control the specific reaction area, reaction volume, and discharge of reaction products. In this process, the sealing control of these two gases is particularly important. Therefore, as an important part of the fuel cell, the sealing component plays the role of sealing gas, and the long-term effectiveness of this component is a prerequisite for ensuring the long-term r...
