Abstract

The invention provides a system and a method for reducing air inflow during idling of a fuel cell, and the system comprises an air filter, an air compressor, an intercooler, a first throttle valve, asecond throttle valve, a humidifier and an FEMC. The first throttle valve is connected with the air compressor in parallel through a bypass pipe, the output end of the air filter is connected with theinput end of the air compressor. The output end of the air compressor is connected with the input end of the intercooler, the output end of the intercooler is connected with the input end of the humidifier, the output end of the humidifier is connected with the input end of the FEMC, and the output end of the FEMC is connected with the input end of the second throttle valve. A pipeline and a throttle valve are additionally arranged in front of an intercooler and an air compressor. Excessive air is shunted before the intercooler, so that the amount of air flowing through the intercooler is reduced, namely the air flowing through the PEMFC is reduced.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a system and method for reducing the air intake amount of fuel cells at idle speed. Background technique [0002] Hydrogen energy is regarded as the ultimate form of human energy because of its zero-emission and pollution-free characteristics. It has been promoted and applied in the fields of fuel cells and fuel cell vehicles. [0003] Proton exchange membrane fuel cell (PEMFC) is currently the mainstream vehicle fuel cell. PEMFCs only need hydrogen and oxygen in the right state to generate electricity. [0004] In order to ensure the sustainability of the vehicle's running state, it is necessary to require the power output of the fuel cell system to be 0 when the vehicle is idling, so it is necessary to control the air intake of the fuel cell. However, the air intake volume of the existing fuel cell air compressor is still too large under the condition of the lowest rotatio...
