Abstract

The invention is concerned with the fuel cell that produces with buckle groupware. It is to burke the double terminal board with the burke piece averagely to generate the average compression rate of the fuel cell gas diffusion fold, which enhance the working performance of the batter and shorten the producing hours and the weight, volume of the battery. The producing method is to locate the average auto-pressing providing producing press on the each fold of the fuel battery group on the weight bearing seat and use the effect of the average pressing to avoid the uneven pressing between each fold and improve the productivity of the battery group.

Description

technical field

[0001] The present invention relates to a fuel cell, in particular to a fuel cell suitable for assembly with fastening components and an assembly method thereof. Background technique

[0002] A traditional fuel cell is composed of a membrane electrode group, a flow field plate, a collector plate, and an end plate. The screw holes are used to clamp the end plate with bolts to fix the fuel cell, and use the entire plane to give a certain torque with the bolts around the end plate, and apply an average pressure to the collector plate and the flow field plate.

[0003] However, in the related known technology, in order to avoid manual stacking and then locking the bolts separately, resulting in uneven pressure, and then causing stack shift, resulting in poor airtight effect between stacks and uneven clamping pressure, The fuel cell stack 100 is assembled with the assembly press 10 . It can be seen from FIG. 1 that the press block 26 of the known assembly press ...
