Description

Technical Field

[0001] This utility model relates to the field of hydrogen fuel cell drainage technology, and in particular to a drainage device for hydrogen fuel cells. Background Technology

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis. Hydrogen and oxygen are supplied to the anode and cathode, respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons and reaches the cathode through an external load. In this process, hydrogen and oxygen react to produce water and generate electrical energy as a byproduct. The water produced is discharged through a drainage device.

[0003] A search revealed that authorization announcement number CN221613933U discloses a drainage device for a hydrogen fuel cell, including a hydrogen fuel cell. A water outlet pipe is provided on one side of the hydrogen fuel cell, and the other end of the water outlet pipe is connected to a water storage tank. A base plate is provided at the bottom of the water storage tank, and a circular perforation is provided at the center of the base plate. A drainage pipe is provided below the circular perforation. Sliding rods are provided on both side walls of the water storage tank, and a sliding assembly is provided between the two sliding rods. The sliding assembly passes through a fixed block and is connected to the two sliding rods. A blocking block is fixedly connected to the lower part of the fixed block. Therefore, this utility model provides a drainage device for a hydrogen fuel cell, which can achieve the effect of completely draining the water in the water storage tank by utilizing the blocking block and the base plate.
