Abstract

The invention relates to an apparatus and a method for regulating pipeline gas, in particular to a technology for quickly regulating temperature and humidity of pipeline gas, belonging to the field offuel cells. The device comprises a gas and steam mixing system and a temperature regulating system, wherein the gas and steam mixing system is respectively provided with two pipelines of gas and steam, the two pipelines are confluent at the nozzle, after spraying-out through the nozzle, mixed temperature regulation is continued and then output is performed, and the temperature regulating system regulates the temperature inside a jacket by regulating the proportion of a heat agent and a refrigerant entering the jacket. The invention can improve the response speed, and in particular provide thequick change control of the temperature and humidity flow in the rated range for the humidifying device after thermal hysteresis is reduced.

Description

technical field [0001] The invention belongs to the field of fuel cells, and in particular relates to a device and method for quickly adjusting the temperature and humidity of pipeline gas. Background technique [0002] Some industrial processes need to raise the temperature and humidify the gas, such as pipeline gas with a certain pressure. Especially for the humidification of the supply gas of the proton exchange membrane fuel cell test platform, it is necessary to carry out rapid temperature and humidity adjustment according to the gas flow, pressure and temperature of the different working conditions of the stack. [0003] For fuel cell stack testing, it is necessary to control the temperature, pressure, humidity, and flow rate of the gas supply to detect various performances of the stack and find out the optimal conditions. Among them, the humidification of the air is mainly realized by bubbling, spray spraying, membrane exchange, steam and so on. However, the current...
