Title:
FUEL CELL COOLING AND VENTILATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/010844
Kind Code:
A1
Abstract:
Disclosed in the present utility model is a fuel cell cooling and ventilating system, comprising an air compressor, an intercooler, a humidifier, a cell stack module and a box body, the box body being provided with a ventilation inlet and a ventilation outlet. The system is characterized in that the intercooler, the humidifier and the cell stack module are all arranged inside the box body; the air compressor is located outside the box body, and the air compressor conveys air to an inlet of the intercooler; cold air output from an outlet of the intercooler is split and output by a main path and a branch path; the cold air from the main path is treated by the humidifier and then sent to an air input port of the cell stack module; and the cold air from the branch path is sent to a cooling channel inlet of the air compressor, and then returns to the ventilation inlet of the box body from a cooling channel outlet of the air compressor so as to purge the box body, so that hydrogen and heat accumulated inside the box body are exhausted from the ventilation outlet. The system integrates cooling of the air compressor and ventilation of the box body, and thus has a simple structure, with less components to be arranged, thereby saving costs.
