Embodiment 1

[0039] Such as Figure 4 As shown, an assembly frame suitable for large-scale rapid assembly and testing of fuel cell stacks, the assembly frame includes a workbench 1, a pressure adjustable pressing device 2, and a positioning guide rod 3, and the workbench is provided with a plate-type table 11 , used to support the pressure-adjustable compression device 2 and the fuel cell stack 4 to be assembled and tested, the pressure-adjustable compression device 2 is arranged at one end of the table 11, and the fuel cell stack 4 is arranged on the table 11 The other end of the positioning guide rod 3 is provided with four, and the positioning guide rod 3 is vertically penetrated on the front and rear end plates 41, 42 of the fuel cell stack 4 along the axial direction, wherein the four positioning guide rods 3 are respectively Set on the left, right and bottom of the front and rear end plates 41, 42 of the fuel cell stack 4 to be assembled and tested, the two on the left and right are ...

Embodiment 2

[0045] Please refer to Figure 4 , In this embodiment, the fuel cell stack 4 is composed of a front end plate, a positive electrode conductive current collector plate, 100 single cells, a negative electrode conductive current collector plate and a rear end plate. The single cell is 206mm high and 206mm wide. Four positioning guide rods 3 are arranged on the assembly frame, two at the bottom (not shown), and two at the left and right. The bottom two are used to support the fuel cell stack. The surface is very smooth, which is conducive to sliding when the fuel cell stack is compressed by the pressure of the compression device. The distance between the left and right two is slightly wider than 206mm by 0.05mm-0.20mm , which is conducive to the tidy assembly of each single battery.

[0046] The pressing device 2 adopts a hydraulic jack type jack 21, and when the pressure of the jack is increased to 10 kg / cm2 by the hand-operated hydraulic lever, the jack 21 will press the rear ...

Abstract

This invention relates to an assembly frame suitable for large scale quick assembling of fuel battery stacks and a test including a working table, a pressure adjustable compression device and a positioning guide rod, among which, said working table is set with a plate mesa for supporting the compression device and the fuel battery stacks necessary for assembly and test, the compression device is set at one end of the mesa, said fuel battery stack is set at the other end, two positioning guide rods vertically pass through the front and back end plates of the stack axially, said compression device has a crown bar driving the back end plate of the stack to press towards the front end plate axially.

Description

technical field [0001] The invention relates to fuel cells, in particular to an assembly frame suitable for large-scale rapid assembly and testing of fuel cell stacks. Background technique [0002] An electrochemical fuel cell is a device that converts hydrogen and oxidants into electrical energy and reaction products. The internal core component of the device is the membrane electrode (Membrane Electrode Assembly, referred to as MEA). The membrane electrode (MEA) is composed of a proton exchange membrane and two porous conductive materials, such as carbon paper, sandwiched between the two sides of the membrane. On the two boundary surfaces of the membrane and the carbon paper, there are even and finely dispersed catalysts for initiating electrochemical reactions, such as metal platinum catalysts. Conductive objects can be used on both sides of the membrane electrode to draw the electrons generated during the electrochemical reaction through an external circuit to form a cu...
