Multi-way parallel self-blended type quick response fuel cell supply device

Abstract

The invention relates to a multi-way parallel self-blended type quick response fuel cell supply device used for a fuel cell. Measurement of multiple characteristics of gas is realized by preparing a multi-way pipeline, and quantity of the measured characteristic items can be flexibly and automatically increased or decreased. By adding a proportional valve in the multi-way pipeline, self blending between environment temperature gas and heated gas and between dry gas and humidified gas can be realized, so that quick response regulation on temperature and humidity of gas required by the fuel cellis realized. The multi-way parallel self blended type quick response fuel cell supply device provided by the invention has the functions of automatically increasing and decreasing gas characteristicmeasurement items, quickly responding and regulating the temperature and humidity of the gas.

Description

technical field [0001] The invention relates to the field of proton exchange membrane fuel cells, in particular to a fuel cell gas supply device. Background technique [0002] The vehicle fuel cell engine uses hydrogen as fuel, and converts the chemical energy in the hydrogen into electrical energy through the fuel cell power generation device and drives the electric motor to provide power for the vehicle. Hydrogen fuel is used by fuel cell engines to only discharge water. It is a green and environmentally friendly new technology, and is considered to be the most promising new electric vehicle technology to replace traditional gasoline, diesel, natural gas and other vehicles. [0003] The key power generation component of the proton exchange membrane fuel cell using hydrogen as fuel is the membrane electrode, and one of the key materials for the membrane electrode is the proton exchange membrane. The proton exchange membrane needs to conduct protons in the presence of water...

Problems solved by technology

[0004] The gas characteristic measurement in the existing fuel cell test system is usually installed once by the manufacturer or laboratory, and it is difficult to achieve flexible self-increase and decrease for the measurement type of gas characteristic; the fuel cell water management is generally controlled by the fuel cell gas humidifier. The gas in the battery is humidified, and the humidification state of the gas is generally controlled by adjusting the water temperature or flow in the humidifier, but the adjustment of the water temperature or flow takes time, and the response speed is generally slow, so it is difficult to achieve rapid and dynamic adjustment of the temperature and humidity of the inlet gas
