Stacking device of proton exchange membrane fuel cell

Abstract

The invention discloses a stacking device of a proton exchange membrane fuel cell. The stacking device comprises a rack, a workbench, a primary pressure applying mechanism, a secondary pressure applying mechanism, a sliding block set and a pressure applying plate set, wherein the workbench is fixed on the upper portion of the rack; the sliding block set comprises two sliding blocks capable of moving on the workbench in an opposite direction; the primary pressure applying mechanism is arranged on the rack, is connected with the sliding block set and can drive the two sliding blocks to move oppositely so as to carry out primary pressure applying; the secondary pressure applying mechanism is connected to the sliding block set, and can drive the two sliding blocks to move oppositely after primary pressure applying so as to carry out secondary pressure applying; the pressure applying plate set comprises two pressure applying plates, wherein each pressure applying plate is connected to one corresponding sliding block. The two modes of the sliding block set are matched with the design of the two pressure applying structures, so that rapid stacking can be realized in the battery stacking process, and by virtue of the two kinds of different pressure applying modes of slow and strong pressure applying, the two ends of the battery can be evenly applied with pressure, and the force applying precision is high, so that the fuel cell can be prevented from being damaged in the force application process and is convenient to assemble.

Description

technical field [0001] The invention relates to the field of proton exchange membrane fuel cells, more specifically, to a stacking device for proton exchange membrane fuel cells. Background technique [0002] The strong demand for clean energy in today's society has led to more and more fuel cells being put into social production and life. A fuel cell is a device that directly converts the chemical energy of hydrogen into electrical energy. It has high efficiency, low noise, and no pollution. And other advantages, in today's society is playing an increasingly important role. The output power voltage of a single proton exchange membrane fuel cell is low, so the fuel cell needs to be assembled into a stack in a certain way when the fuel cell is applied. The main components of the stack include bipolar plates, membrane electrodes, end plates and fasteners. The accuracy and uniformity of the force during the assembly process of the stack determines the performance of a stack. T...

Problems solved by technology

There are some problems in the battery stacking devices used by fuel cell manufacturers today. For example, the compression force on the plates is uneven, resulting in cracks at one end of the plates or incomplete compression of the plates during the pressing process; The pressing speed of the device is slow, which wastes the operator's time and affects the efficiency of production. The battery stacking device is too heavy to move easily. During the pressing process, the control accuracy of the fuel cell plate is low, which affects the quality of the finished fuel cell.
