Description

Technical Field

[0001] This utility model relates to the field of hydrogen fuel cell technology, specifically to a hydrogen fuel cell with a composite plate structure. Background Technology

[0002] Hydrogen fuel cells are power generation devices that directly convert the chemical energy of hydrogen and oxygen into electrical energy. Hydrogen fuel cells have wide applications in many fields, such as automotive energy and aerospace energy, and are considered one of the main vehicle power sources in the post-fossil energy era, which is of great significance for promoting the transformation of energy and power.

[0003] For example, the Chinese authorized patent CN217009262U (An Integrated Hydrogen Fuel Cell Stack Structure) includes: a housing, a fuel cell stack disposed within the housing, a controller for controlling the output of the fuel cell stack, and a solenoid valve. An air inlet and an air outlet are provided on one side of the housing. The controller is installed at the bottom of the fuel cell stack with a gap between the controller and the fuel cell stack. The solenoid valves are positioned opposite each other on both sides of the fuel cell stack. Clamping plates are positioned opposite each other on the base. One end of the clamping plate is movably connected to the bottom of the housing, and the end of the clamping plate away from the bottom of the housing is movably connected to the fuel cell stack. This invention reduces the overall space occupied by integrating the fuel cell stack, solenoid valve, and controller within the housing.

[0004] However, most existing hydrogen fuel cell stacks are fixed to the protective shell with bolts, resulting in a simple fixing structure. Different sizes of hydrogen fuel cells need to be installed inside different protective shells, leading to poor installation applicability. Therefore, this does not meet the current requirements. To address this, we propose a hydrogen fuel cell with a composite plate structure. Utility Model Content

[0005] The purpose of this invention is to provide a hydrogen fuel cell with a composite plate structure, in order to solve the problems mentioned in the background art, that most existing hydrogen fuel cell stacks are fixed to the protective shell by bolts, resulting in a single fixing structure, and that hydrogen fuel cells of different sizes need to be installed inside different protective shells, leading to poor installation applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen fuel cell with a composite plate structure, comprising: a protective shell, wherein a battery stack is disposed inside the protective shell, and an installation assembly is disposed outside the battery stack; the battery stack includes an electrolyte membrane and a negative electrode plate, wherein the negative electrode plate is located at the upper end of the electrolyte membrane, and a positive electrode plate is disposed at the lower end of the electrolyte membrane; and end plates are disposed at the upper end of the negative electrode plate and the lower end of the positive electrode plate.

[0007] Preferably, the mounting assembly includes a positioning frame and an adjustment frame, and the positioning frame and the adjustment frame are located on both sides of the battery stack. The upper end of the positioning frame is provided with a threaded fastener, and the positioning frame is fixed to the protective shell by the threaded fastener.

[0008] Preferably, the outer surfaces at both ends of the positioning frame are provided with stabilizing slots, and one end of the stabilizing slot extends out of the positioning frame, and one side of the stabilizing slot is provided with a threaded groove.

[0009] Preferably, the inner walls at both ends of the adjustment frame are provided with stabilizing inserts, and the stabilizing inserts are inserted along the stabilizing slots, and both the stabilizing inserts and the stabilizing slots are T-shaped.

[0010] Preferably, both ends of the adjusting frame are provided with adjusting grooves, and the adjusting grooves penetrate the adjusting frame. A fixing bolt is provided on one side of the adjusting groove, and one end of the fixing bolt passes through the adjusting groove and is threadedly connected to the threaded groove.

[0011] Preferably, the inner wall of the adjusting frame near the corner is provided with a pressing seat, and the pressing seat is heat-fused to the adjusting frame.

[0012] Preferably, the protective housing has a top cover at its top, one end of the top cover has a negative terminal and the other end has a positive terminal. The upper surface of the protective housing has a handle groove, and a handle is provided inside the handle groove. Both ends of the handle are rotatably connected to positioning seats.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets an installation component on the outside of the battery stack. The installation component mainly consists of a positioning frame and an adjustment frame. When fixing the battery stack, the positioning frame is fixed to the protective shell by threaded fasteners and is fixed on one side inside the protective shell. The battery stack is clamped by the positioning frame and the adjustment frame. When the other end of the battery stack contacts the adjustment frame, the fixing bolt is tightened. One end of the fixing bolt passes through the adjustment groove and is threaded to the threaded groove to fix the adjustment frame and the positioning frame, and the battery stack is squeezed and fixed. By adjusting the distance between the positioning frame and the adjustment frame, the fixing space can be adjusted. It is suitable for fixing battery stacks of different sizes, improving flexibility and applicability. It solves the problem that most existing hydrogen fuel cell stacks are fixed to the protective shell by bolts, the fixing structure is simple, and hydrogen fuel cells of different sizes need to be installed inside different protective shells, resulting in poor installation applicability.

[0015] (2) By setting stabilizing slots on the outer surfaces of both ends of the positioning frame and stabilizing inserts on the inner walls of both ends of the adjustment frame, the stabilizing inserts of the adjustment frame are inserted along the stabilizing slots. Both the stabilizing inserts and the stabilizing slots are T-shaped, which improves the stability of the connection between the positioning frame and the adjustment frame, making it less prone to positional shift and separation, thus ensuring the stability of fixing the battery stack.
