Air supply system experiment device for proton exchange membrane fuel cell for automobile

Abstract

The invention relates to an air supply system experiment device for a proton exchange membrane fuel cell for an automobile. The device comprises a filter, a compressor, an intercooler, a heater, a humidifier, a gas and water separator, a fuel cell pile and a control computer. The filter is sequentially connected with the compressor, the intercooler, the humidifier and an air inlet of the fuel cell pile through a pipeline and is connected back to an inlet of the compressor by means of an air outlet of the fuel cell pile sequentially through the humidifier and the gas and water separator, the heater and the intercooler are arranged in parallel, a plurality of electromagnetic valves and induction units are further arranged on the pipeline, and the electromagnetic valves and the induction units are both connected with the computer through a circuit. Compared with the prior art, the device is simple and compact in structure, the electromagnetic valves are combined for use and controlled in a combined mode, various fuel cell pile cooling loop structures are configured, and the purposes of fast matching part parameters of a system and fast verifying a control algorithm are achieved.

Description

technical field [0001] The invention belongs to the field of vehicle power technology and application, and relates to an experimental device for an air supply system of a fuel cell, in particular to an experimental device for an air supply system of a proton exchange membrane fuel cell for a vehicle. Background technique [0002] Fuel cells mainly generate electricity directly through the electrochemical reaction of fuel (such as hydrogen). Because fuel cells have a series of excellent performances such as high efficiency, zero emissions, stable operation, and no noise, they are regarded as the most likely source of power for future automobiles. Fuel cell vehicles are the development trend of the future automobile industry. [0003] Since the fuel cell uses electrochemical reactions to convert chemical energy into electrical energy, it is not limited by the Carnot cycle, and its theoretical efficiency can reach up to 80%. Due to the influence of activation polarization, ohm...
