Abstract

The invention relates to a pile bundling device for automobile fuel cells. The pile bundling device comprises a steel belt (1), a pretension end plate unit, and an end plate (6), which are arranged in sequence. The pretension end plate unit and the end plate (6) are arranged on the left and right sides of a pile (5) respectively, ratchet wheel units are arranged on the upper and lower sides of the end plate (6), the steel belt (1) is U-shaped and comprises a bottom and two side wings, and the side wings are welded with the two ratchet wheel units respectively. Compared with the prior art, the pile bundling device adopts surface clamping force and allows more uniform pressure distribution and deformation on the internal film electrode in the pile.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a device for bundling fuel cell stacks for vehicles. Background technique [0002] The increasingly severe energy and environmental challenges have made the transformation of transportation energy and power a global consensus. The development of new energy fuel cell vehicles is considered to be one of the important links in the transformation of transportation energy and power, and has attracted much attention. Because proton exchange membrane fuel cells have the advantages of no pollution, high efficiency, wide application, low noise, fast energy replenishment, and modular structure, they are considered to be one of the most ideal power sources to replace traditional internal combustion engines. The core component of the fuel cell vehicle power system is the proton exchange membrane fuel cell stack, referred to as the stack. It consists of two or more (even hundreds) of batt...
