A pressure reducing and stabilizing valve applied to the preparation of fuel cells

Abstract

A pressure reducing and stabilizing valve applied to the preparation of fuel cells, comprising a valve body, a cylindrical first valve core and a second valve core, the valve body is formed with a first valve hole and a second valve hole, the first valve hole A pressure stabilizing groove is formed on the valve body between the valve body and the second valve hole, the first valve core and the second valve core are inserted into the first valve hole and the second valve hole of the valve body respectively, the first valve hole and the second valve hole The lower ends of the two valve holes are respectively inserted and fixed with the first cushion block and the second cushion block, and the lower ends of the first valve core or the second valve core are respectively pressed against the first cushion block or the second cushion block, and the first cushion block and the upper end of the second spacer are respectively pressed against the first compression spring and the second compression spring, and the upper ends of the first compression spring and the second compression spring are respectively pressed against the first adjustment knob and the second adjustment knob, and the first adjustment The knob and the second adjusting knob are respectively screwed into the first valve hole and the second valve hole of the valve body. The structure of the valve is simple and small, and the decompression and voltage stabilization are integrated on the same valve body; it is suitable for the working requirements of hydrogen fuel cells.

Description

Technical field: [0001] The invention relates to the technical field of fuel cells, and more specifically relates to a pressure reducing and stabilizing valve applied to the preparation of fuel cells. Background technique: [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. Among them, the hydrogen fuel cell uses the chemical element hydrogen to manufacture a battery for storing energy. The basic principle is the reverse reaction of electrolyzing water, supplying hydrogen and oxygen to the cathode and anode respectively, and hydrogen diffuses outward through the cathode and reacts with the electrolyte. Electrons reach the anode through an external load. At present, when the hydrogen fuel cell is working, the hydrogen and oxygen from the storage tank need to be decompressed and stabilized before entering the power generation module of the fuel cell, otherwise it will ...

AI Technical Summary

Problems solved by technology

At present, when the hydrogen fuel cell is working, the hydrogen and oxygen from the storage tank need to be decompressed and stabilized before entering the power generation module of the fuel cell, otherwise it will impact the power generation module of the fuel cell and cause damage to the power generation module. The battery as a whole is developing in the direction of small size and weight reduction, so it is necessary to design a small pressure reducing and stabilizing valve integrating pressure reducing and stabilizing
