Abstract

The invention relates to a pressure-bearing assembling structure of a fuel cell module, which comprises the fuel cell module, a first pressure-bearing end plate, a first-pole collector plate, a second pressure-bearing end plate, a second-pole collector plate and a pressing structure, wherein the fuel cell module comprises a first-pole side, a second-pole side and at least one cell monomer; the first pressure-bearing end plate is connected with the first-pole side of the fuel cell module through a first end plate and the first-pole collector plate; the second pressure-bearing end plate is connected with the second-pole side of the fuel cell module through a second end plate and the second-pole collector plate; the pressing structure consists of a pressing plate and a pair of lateral plates, wherein an opening end is formed between the two lateral plates, the pressing plate supports against one plate surface of the second pressure-bearing end plate, and the opening end is positioned at both sides of the first end plate and connected with a combination part of the first end plate through a positioning structure.

Description

technical field [0001] The invention relates to the design of a battery assembly structure, in particular to a pressure-bearing assembly structure of a fuel cell module. Background technique [0002] A fuel cell is a device that generates electricity and water through an electrochemical reaction between hydrogen-containing fuel and air. The operating principle of a fuel cell, taking a proton exchange membrane fuel cell as an example, includes multiple battery cells, each cell is equipped with a proton exchange membrane (Proton Exchange Membrane, PEM) in the center, and a layer of catalyst is installed on each side. A gas diffusion layer (Gas DiffusionLayer, GDL) is arranged on the outside, and an anode bipolar plate and a cathode bipolar plate are respectively arranged on the outermost side, and these components are tightly combined with a predetermined contact pressure to form a battery monomer. [0003] While the fuel cell performs the aforementioned electrochemical reac...
