Effectively fix the structure of the fuel cell stack

Abstract

The invention discloses a structure for effectively fixing a fuel cell unit. The structure comprises the fuel cell unit, a lower supporting plate and an upper supporting plate, wherein the lower supporting plate and the upper supporting plate are used for fixing the fuel cell unit. Grooves A for placing the fuel cell unit are formed in the lower supporting plate and the upper supporting plate, a storage slot for surrounding the fuel cell unit inside is connected onto the lower supporting plate, a buffer plate is arranged between the storage slot and the fuel cell unit and comprises a pressure dispersion plate and a wavy elastic buffer plate positioned on the pressure dispersion plate, the buffer plate contacts with the side face of the fuel cell unit, a plurality of small through holes are formed in the buffer plate, a groove B for clamping the buffer plate is formed in the upper supporting plate, a connecting plate is connected onto the upper supporting plate, the storage slot internally sleeves the connecting plate, and the fuel cell unit and the buffer plate are positioned on the grooves A and the groove B when the storage slot internally sleeves the connecting plate.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a structure for effectively fixing a fuel cell group. Background technique [0002] With the development of fuel cell technology, its application fields are becoming wider and wider. At present, some types of drones use fuel cell packs to power motors and other electronic devices. However, after the fuel cell is installed in the drone, its fixing problem has not been paid attention to. Since the fuel cell has not been well fixed, it is very easy to have subtle vibrations during take-off, landing and aerial photography. Over time , it will further cause the instability of the performance of each single cell of the fuel cell stack. [0003] Moreover, fuel cells are more and more popular and used by people because of their advantages such as high energy conversion efficiency, low noise, low carbon, zero emissions, flexible and convenient use, low operating temperature, and high energy density.

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that when the UAV is in use, it is easy to shake and easily lead to instability of the performance of each single cell of the fuel cell stack. However, in the existing bolt fixing mode, the vibration will easily cause the nuts of the bolts to loosen. The contact resistance of the electric stack increases, resulting in a decrease in the performance of the electric stack and a reduction in the life of the electric stack. In severe cases, the electric stack leaks, and an explosion may occur due to hydrogen leakage.

The purpose is to provide a structure for effectively fixing the fuel cell stack and solve the problem of fixed installation of the fuel cell
