Positioning tool for assembling hydrogen fuel cell and use method of positioning tool

Abstract

The invention discloses a positioning tool for assembling a hydrogen fuel cell and a use method thereof.The positioning tool for assembling the hydrogen fuel cell comprises a bottom plate used for bearing a hydrogen fuel cell assembly, mounting plates used for fixing are arranged on the periphery of the bottom plate, limiting assemblies are arranged on the two sides of the bottom plate, and connecting assemblies are connected to the two sides of one end of the bottom plate; the top end of the connecting assembly is connected with a supporting rod, the top end of the supporting rod is connected with a top seat, and one side of the top seat is provided with a tamping structure used for connecting the hydrogen fuel cell assemblies. Through the arranged tamping structure, a control motor drives a threaded transmission shaft to rotate and drives an extrusion plate at the bottom end of a barrel plate to move downwards to tamp hydrogen fuel cell assemblies, so that all the assemblies are continuously extruded, connected and sealed, and compared with a traditional mode that the assemblies are transferred after assembly, more convenience is achieved; the extrusion amount is convenient to control, and excessive extrusion is prevented from affecting the connecting effect.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a positioning tool for assembling hydrogen fuel cells and a method for using the same. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load. [0003] Hydrogen fuel cells are environmentally friendly. It uses electrochemical reaction instead of combustion (gasoline, diesel) or energy storage (battery) - the most typical traditional backup power solution. Combustion releases pollutants like COx, NOx, SOx gas and dust. As mentioned above, fuel cells only produce w...

Problems solved by technology

[0004] Most of the existing hydrogen fuel cells have the following disadvantages during assembly: 1. The assembled hydrogen fuel cells need to be transferred and then sealed, the sealing efficiency is low and the effect is poor; 2. It is not possible to flexibly target different types of hydrogen Fuel cells are positioned so that their components are offset during assembly, affecting the connection
