The invention discloses a high-pressure atomization humidifier for fuel cell test equipment, which relates to the technical field of fuel cells and comprises a tank body, a high-pressure atomization device, a gas separation device, a liquid heating device, a gas outlet pipe arranged at one end of the tank body and an air inlet pipe arranged on one side of the tank body, the gas outlet pipe is communicated with the interior of the tank body, the air inlet pipe is communicated with the gas separation device, the liquid heating device is arranged on the side, away from the gas outlet pipe, of the gas separation device, and the high-pressure atomization device is arranged on the side, close to the gas outlet pipe, of the gas separation device and connected with the liquid heating device. According to the system, the air entering the fuel stack can be humidified, pressurized and heated in advance, meanwhile, the humidity, the temperature and the pressure can be controlled, the humidified air can directly enter the fuel stack to be used, water vapor or condensate water generated in the humidifying process can be recycled, resources can be saved, and the cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a high-pressure atomizing humidifier for fuel cell test equipment. Background technique [0002] As the core component of a fuel cell vehicle, the performance of the fuel cell directly affects the use of the vehicle; the factors affecting the performance of the fuel cell are not only the structural characteristics and material characteristics of the fuel cell such as the flow field structure, catalyst performance, and membrane electrode performance, but also Affected by operating conditions such as humidity, flow, pressure, temperature, etc.; the humidity condition not only affects the moisture distribution inside the stack and the ionic conductivity of the membrane, but also affects the internal fuel gas pressure distribution and affects the mass transfer effect. Therefore, it is necessary to design Humidity is tested and controlled accordingly to obtain optimal operating par...
