Abstract

The invention discloses a humidifier and a fuel cell humidification system.The humidifier comprises a shell, a core and a spoiler, the shell is provided with a cavity, a first inlet, a second inlet and an outlet, and the first inlet, the second inlet and the outlet are all communicated with the cavity; the shell is provided with a first inlet and an outlet, the first inlet and the outlet are oppositely arranged along the length direction of the shell, the outlet is arranged adjacent to the first inlet, the core body is arranged in the cavity, the outer peripheral surface of the core body and the inner peripheral surface of the shell are arranged at an interval, the core body is arranged adjacent to the second inlet, and the core body is arranged in the cavity. The core body is arranged in the cavity, the cross section area of the core body is gradually increased in the direction towards the first inlet, and the spoiler is arranged in the cavity and arranged at the end, close to the outlet, of the core body. The humidifier has the advantages of being simple in structure, low in cost, good in humidifying effect and the like.

Description

technical field [0001] The invention relates to the field of manufacturing fuel cells, in particular to a humidifier and a fuel cell humidification system. Background technique [0002] During the electrochemical reaction of the fuel cell, the proton exchange membrane needs to maintain a certain humidity. The fuel cell humidification methods include bubbling humidification, enthalpy wheel humidification, spray humidification, and hollow fiber membrane tube humidification technology. [0003] In related technologies, fuel cell humidifiers are relatively expensive and have a short service life. Contents of the invention [0004] The present invention is based on the inventor's discovery and recognition of the following facts and problems: [0005] In the related art, the fuel cell humidification system, such as figure 1 As shown, the air is filtered in the air filter, compressed in the air compressor, cooled in the intercooler, humidified in the tube side of the hollow fib...
