A packaging structure for a fuel cell stack

Abstract

The application provides a packaging structure for a fuel cell stack, and belongs to the technical field of fuel cells, and solves the problem that the prior art does not consider the instability of packaging force and the easy loosening of the packaging structure. The packaging structure comprises a locking nut, a packaging shell, a packaging force adjusting mechanism, an elastic mechanism, an insulating plate and a stack core. The packaging shell adopts a hollow shell structure with one side being open, and the opening side of the shell structure is a mounting face provided with a positioning mounting hole. One side of the packaging force adjusting mechanism is provided with a locking external thread connected with the locking nut, and the other side is provided with a horizontal pressure bearing surface in contact with the elastic mechanism. One side of the stack core is sequentially fixed with the insulating plate, the elastic mechanism and the packaging force adjusting mechanism, and then the whole is inserted into the packaging shell along the side direction, so that the locking external thread of the packaging force adjusting mechanism is pressed through the locking nut after being passed out of the positioning mounting hole, and the other side is fixedly connected with the packaging shell. The structure has the functions of anti-loosening and external adjustment of the pressing force.
