Abstract

The invention relates to the field of a proton exchange membrane fuel cell, in particular to a fuel cell stack assembly device and assembly method. The device mainly comprises a guide rail fixing seatplate (1), a positioning rod (3), a sliding seat plate (4), a primary press mechanism, a second press mechanism, a sliding block (6), a guide rail rack (9), a guide rail surface (13) and an electricstack end plate press block, wherein the guide rail fixing seat plate (1) is arranged at one end of the guide rail rack (9), the guide rail surface (13) is arranged on the guide rail fixing seat plate(1), the sliding seat plate (4) is connected with the secondary press mechanism, the positioning rod (3) is connected with the sliding seat plate (4), and the primary press mechanism and the second press mechanism are connected via the sliding block (6). With the adoption of the fuel cell stack assembly device, a battery can be prevented from being pressed and damaged due to non-uniform pressureor misoperation during the battery assembly process, meanwhile, the battery can be accurately pressurized, and the assembly pressure is ensured.

Description

technical field [0001] The invention relates to the field of proton exchange membrane fuel cells, in particular to a fuel cell stack assembly device and assembly method. Background technique [0002] The output power voltage of a single proton exchange membrane fuel cell is low, so when the fuel cell is applied, several single cells are connected in series to output external power, and the assembly of the fuel cell stack affects the external output of the fuel cell. The assembly efficiency and quality of the fuel cell stack directly affect the external output of the fuel cell. The conventional method uses a pressure mechanism to pressurize the battery stack, uses positioning rods and other devices for positioning, and then locks with screws, which is inefficient and difficult to guarantee assembly accuracy. [0003] Patent CN104835978A proposes an automatic assembly system for proton exchange membrane fuel cell stacks. The assembly system can realize the continuity, automa...
