Abstract

The invention discloses an automatic fuel cell stack assembling and detecting device, which comprises a rack, a material conveying assembly used for conveying different assemblies forming an electricpile to a designated position, an electric pile output assembly used for outputting assembled electric piles, a pressing assembly used for providing stable and accurate pressure for the electric piles, an automatic lifting assembly used for enabling a hydraulic workbench of the pressing assembly to be located at different heights so as to adapt to electric piles of different specifications, a limiting assembly used for limiting the stacking position of an electric pile assembly on the bottom plate of the rack, an automatic tightening assembly comprising an electric screwdriver, and an air tightness detecting assembly comprising an air cylinder, a connecting pipeline of the air cylinder and a quick-screwing plug and used for detecting the air tightness of the electric piles. The device is high in automation degree, manpower is greatly saved, and the phenomenon that the parts of an electric pile are stressed unevenly is avoided. A positioning pin can be pulled out stably by an automaticpin pulling device, and damage to the electric pile assembly in the manual pin pulling process is avoided.

Description

technical field

[0001] The invention relates to the technical field of fuel cell stacks, in particular to a fuel cell stack automatic assembly detection device. Background technique

[0002] Proton exchange membrane fuel cell (PEMFC) has the advantages of low operating temperature, fast start-up and shutdown, high energy density, etc., and has a good application prospect in mobile power, vehicles and other equipment.

[0003] A proton exchange membrane fuel cell consists of a collector plate, a flow field plate, a gas diffusion layer (GDL), a catalytic layer and a proton exchange membrane. Due to the limited voltage and power generated by a single cell, it is often necessary to connect multiple single cells in series to form a fuel cell stack in order to meet the working requirements.

[0004] The components of the PEMFC stack need to be assembled by applying pressure from the outside. Since the gas diffusion layer (GasDiffusion Layer, GDL) is a porous structure and its ela...
