[0036] With reference to Figure 1 and Figure 2The hydrogen cylinder 1 is provided with a fixing assembly 4 at both ends, which is used for fixing the hydrogen cylinder 1. The fixing assembly 4 comprises a first mounting piece 5 and a second mounting piece 6, which are symmetrically arranged and have the same structure. Since the hydrogen cylinder 1 may expand due to temperature change, the width of the first mounting piece 5 arranged at one end of the hydrogen cylinder 1 is equal to that of the bottle mouth 3, and the width of the second mounting piece 6 arranged at the other end of the hydrogen cylinder 1 is also equal to that of the bottle mouth 3, so that the hydrogen cylinder 1 can be completely positioned. The width of the first mounting piece 5 arranged at the other end of the hydrogen cylinder 1 is slightly smaller than that of the bottle mouth 3, and the width of the second mounting piece 6 arranged at the other end of the hydrogen cylinder 1 is also slightly smaller than that of the bottle mouth 3, so as to leave space for the expansion of the hydrogen cylinder 1.
