Abstract

The invention discloses an assembly structure of a fuel cell stack, and relates to the technical field of fuel cells. The assembly structure comprises a stack mechanism, a gas port end plate and an assembly outer frame. The bottom of the assembly outer frame is provided with an end plate mechanism, a frame opening of the assembly outer frame is provided with a lap joint table, the gas port end plate is matched with the lap joint table, and the lap joint table is provided with a plurality of connecting holes. A pull rod for connecting the air port end plate and the assembly outer frame is arranged in the connecting hole. The end plate mechanism comprises an elastic assembly, an adjusting assembly and two limiting assemblies, the adjusting assembly is arranged at the bottom of the assembling outer frame, and the elastic assembly is installed at the upper end of the adjusting assembly. The two limiting assemblies are arranged on the two sides of the interior of the assembling outer frame correspondingly and matched with the adjusting assembly. On one hand, the integration level of the galvanic pile module is improved, production and assembly are facilitated, and on the other hand, the protection level of the galvanic pile is increased.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to an assembly structure of a fuel cell stack. Background technique [0002] After the traditional fuel cell is assembled with the end plate and the stack, it is necessary to use the stack fasteners (screws, pull plates, etc.) and insert the casing outside the stack to form a complete stack module. However, the existing electric stack fastening and casting casing are independent of each other, which makes the connection between the various parts small. On the one hand, the assembly steps are increased, which makes the assembly efficiency of the electric stack low, and on the other hand, it also reduces the impact of the casing on the electricity. The heap's protection level. Contents of the invention [0003] The purpose of the present invention is to provide an assembly structure of a fuel cell stack to solve the technical problems of low integration and low protection level ...
