A fuel cell parameter control system and its working method

Abstract

The invention discloses a fuel cell parameter control system. The fuel cell parameter control system mainly comprises an air compressor, a pressure reducing valve, a pressure gauge, a filter, a gas supply control valve, a flow meter, a humidification path control valve, a humidifier, a water supplying control valve, a water replenisher, a manually operated valve, a dry gas path control vale, a pressure sensor, a temperature sensor, a fuel cell stack, a pressure sensor, a back pressure valve, a water tank, a PC end control and display device, a hydrogen cylinder and a nitrogen cylinder. The system can test a single parameter of a fuel cell stack system, has a safe use method and stable performances, can detect the performance parameters of the fuel cell under a single variable, and realizes accurate and comprehensive detection of cell stack performances. After a test reaction of the fuel cell, only water is produced and any pollutants are avoided so that zero discharge of pollutants is realized. The invention also provides a working method of the fuel cell parameter control system.

Description

technical field [0001] The invention belongs to the field of fuel cell testing, in particular to a fuel cell parameter control system and a working method thereof. Background technique [0002] A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy, with only electrochemical reactions and no combustion process. [0003] A fuel cell can be an ideal all-solid-state mechanical structure, i.e. no moving parts, such a system would potentially have high reliability and long life, and the fuel cell generates water when fueled by hydrogen and oxygen, which is pollution-free and recyclable use. [0004] Fuel cells have the advantages of high efficiency, no pollution, long life and high reliability, and can be used as a substitute for automobile internal combustion engines, and can also be used in small centralized power supply or decentralized power supply systems. Because fuel cells directly convert chemical energy into electrical energy,...

Problems solved by technology

The patent (CN201210028345) shows that in the fuel cell stack control system, there is no feedback adjustment when controlling various parameters, which will cause a large error, and the safety device is not set properly. If a problem is found, it will stop working immediately, and the Causes gas residues, will damage the experimental equipment and pose a great danger to personnel safety, and the safety needs to be improved
