In the assembling operation process, the sealing plate 12 is firstly detached from the housing 11, then an end feeding port communicated with the inner cavity 111 is formed at the original assembling position of the sealing plate 12, then the battery pieces 13 are placed into the inner cavity 111 one by one from the feeding port, the auxiliary guide piece 131 on each battery piece 13 is aligned and embedded with the corresponding main guide piece 112 in place, then the battery pieces 13 are sequentially stacked and arranged in order, after enough battery pieces 13 are stacked in place and arranged in order, the sealing plate 12 is aligned and assembled to the feeding port again, and the sealing plate 12 and the housing 11 are reliably assembled in place, so that the whole assembling process of the fuel battery assembly can be completed. The assembling process is simple and convenient to operate and high in efficiency, and accurate alignment assembly between each cell piece 13 and the inner cavity 111 can be realized through alignment matching of the main guide piece 112 and the auxiliary guide piece 131 in the assembling process, so that the overall assembling precision of the fuel cell assembly is obviously improved; simultaneously, the extension structure of each main guide 112 makes it have the strengthening rib effect concurrently, can effectively improve fuel cell assembly's overall assembly structural strength especially can effectively avoid the deformation phenomenon that causes main part position such as casing 11 middle part to take place because of reasons such as expend with heat and contract with cold in the follow-up equipment use, thereby is showing and improves fuel cell assembly's structural strength and reliability guarantee its stability in use.

Further, there are at least two main guides 112, and the main guides 112 are parallel to each other. The number of the at least two main guide pieces 112 is enough to ensure that the main guide pieces 112 which are parallel to each other stably and reliably limit the cell pieces 13, and the stacking arrangement effect and the installation precision of the cell pieces 13 are ensured, so that the assembly strength and the assembly integration degree of the fuel cell assembly are further improved, and the whole structure of the fuel cell assembly is less prone to deformation.

In practical applications, if the most basic assembly efficiency of the fuel cell module is to be ensured, the number of the main guides 112 is 1, and accordingly, the number of the sub-guides 131 on each cell piece 13 is also 1, but the number of the main guides 112 is not limited to the above, and may be any number as long as the practical use requirements of the fuel cell module can be satisfied.

Specifically, at least two primary guides 112 are located on the bottom surface of the internal cavity 111. The main guide part 112 is arranged on the bottom surface of the inner cavity 111, which is beneficial to further improving the structural rigidity of the fuel cell assembly, especially the structural rigidity of the middle part of the fuel cell assembly, so that the deformation of main body parts such as the shell 11 and the like caused by expansion with heat and contraction with cold in the subsequent use process is further avoided, and the structural reliability and the working stability of the fuel cell assembly are ensured.
