Abstract

The invention discloses a fuel cell air supply system. The fuel cell air supply system comprises a fuel cell pile used for performing power generation through an electrochemical reaction, an air compressor used for conveying air to the fuel cell pile, a motor used for driving the air compressor to work, an electric power conversion apparatus used for regulating the electric power supplied to the motor, a temperature regulation apparatus and a humidity regulation apparatus used for regulating the temperature and humidity of the supplied air to satisfy target parameters, a sensor assembly used for measuring the pressure, temperature, humidity and flow of the supplied air, and the rotary speed of the air compressor, a bypass branch used for discharging the residual air in the flow, a bypass valve used for controlling the starting area of the bypass branch, an air filtering apparatus used for filtering impurities from the supplied air, and a controller used for controlling operation of each module. By taking a negative electrode air inlet system as one integrated body to perform independent consideration and control, air with the most suitable parameters is supplied to the fuel cell pile accurately.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell air supply system and a control method. Background technique [0002] A fuel cell is an electrochemical device that relies on the electrochemical reaction between the oxidant gas of the cathode and the fuel gas of the anode to generate electricity. It is not limited by the efficiency of the Carnot cycle and can operate continuously for a long time when the reaction gas is sufficient. And no pollution, zero emissions. In recent years, the research on the application of fuel cell technology to various electric power equipment has attracted the attention of governments, enterprises and scientific research institutions of various countries. [0003] As one of the reactants, the cathode oxidant gas, its pressure, flow rate, temperature, humidity and other parameters have a direct impact on the performance of the entire fuel cell system. A fuel cell operating at high e...
