The application provides a humidifying and silencing composite device and a fuel cell system, which comprises a humidifier, a silencing assembly and an air outlet chamber. The humidifier comprises a cavity, the cavity is provided with a wet air inlet and a wet air outlet, one side of the cavity is provided with a dry air inlet, the other side of the cavity is provided with a dry air outlet, the silencing assembly is arranged on the dry air inlet and comprises a silencing chamber and a dispersion pipe, the dispersion pipe is arranged in the silencing chamber from outside to inside, and the air outlet chamber is arranged on the dry air outlet, wherein the air outlet chamber is provided with an air outlet pipe, the dispersion pipe is provided with a micro-perforated structure arranged around the dispersion pipe, the micro-perforated structure comprises a plurality of uniformly distributed micro-holes, and the aperture and the number of the micro-holes are set according to the silencing frequency. The front end cover and the rear end cover of the existing humidifier are removed and replaced by the silencing assembly and the air outlet chamber, so that the humidifier and the silencer are combined, the dry air can be humidified and de-noised, the volume of the humidifier is not changed greatly compared with the existing humidifier, and the space of the proton exchange membrane fuel cell system is greatly saved.

This invention relates to a two-stage back pressure valve cathode air pressure regulation architecture for fuel cells, comprising an air filter, an air compressor, an intercooler, a humidifier, and a fuel cell stack connected in sequence. The key feature is that a primary back pressure valve is installed on the air pipeline between the fuel cell stack and the humidifier, and a secondary back pressure valve is installed on the air pipeline after the humidifier. By installing a primary back pressure valve between the fuel cell stack and the humidifier, and a secondary back pressure valve after the humidifier, this invention achieves coordinated regulation of air pressure and humidity, effectively solving the problems of decoupling humidity and pressure control and poor responsiveness in existing technologies, and improving the stability and dynamic response capability of the fuel cell system.
