Description

Integrated intercooler and throttle humidifier Technical Field The utility model relates to the technical field of automobile fuel cells, in particular to an integrated intercooler and throttle humidifier. Background Hydrogen fuel cells are becoming increasingly interesting as an efficient and clean energy conversion device for use in the automotive field. The proton exchange membrane of the core component can keep good proton conductivity under a proper humidity condition, when the proton exchange membrane is too dry, the proton conductivity is rapidly reduced, so that the internal resistance of the battery is increased, the output power is reduced, and when the proton exchange membrane is excessively wet, flooding phenomenon can be caused, gas diffusion is blocked, and the battery performance is also reduced. Therefore, it is important to precisely control the humidity of the reaction gas entering the hydrogen fuel cell, and the intercooler operates on the principle of cooling high-temperature charge air through heat exchange of air-coolant to increase air density and increase the intake air amount of the engine, thereby improving the power and torque of the engine.
