Abstract

The application provides a hydrogen concentration hardware detection circuit and a fuel cell control system. The concentration comparison unit in the circuit is used to receive and output the concentration comparison signal to the driver according to the comparison relationship between the hydrogen concentration signal and its own concentration preset range. Control unit; the drive control unit is used to output an abnormal signal when the concentration comparison signal indicates that the hydrogen concentration is abnormal, so as to control the key actuators in the hydrogen supply channel to disconnect and stop the hydrogen supply through the corresponding control drive circuit; that is, the present application The hydrogen concentration hardware detection circuit provided can output an abnormal signal through the hardware circuit when the hydrogen concentration is abnormal, so that the corresponding control drive circuit can timely control the key actuators in the hydrogen supply channel to disconnect and stop supplying hydrogen to the fuel cell, which solves the problem of The existing software detection method has the problems of high probability of failure to obtain hydrogen concentration and low reliability; and compared with the software detection method in the prior art, the timeliness of hardware detection is higher.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a hydrogen concentration hardware detection circuit and a fuel cell control system. Background technique [0002] With the continuous development of new energy technologies, fuel cells that use hydrogen as energy and produce electricity through the chemical reaction of hydrogen and oxygen are widely used in the automotive industry. After the fuel cell engine sends hydrogen to the anode plate of the fuel cell, an electron in the hydrogen atom is separated through the action of the catalyst, and the hydrogen ion that has lost the electron passes through the proton exchange membrane and reaches the cathode plate of the fuel cell, and The oxygen atoms and hydrogen ions recombine to form water. Since the oxygen supplied to the cathode plate can be obtained from the air, as long as hydrogen is continuously supplied to the anode plate, the car can be continuously supplied with electr...
