Automatic calibration system and method for control parameters of fuel cell

The invention discloses an automatic calibration system and method for fuel cell control parameters, and relates to the technical field of fuel cell control, and the system comprises a fuel cell system which is divided into a hardware component and a software component. Wherein the hardware part comprises a fuel cell system controller, a fuel cell sensor, an electronic load, a low-temperature test box and a computer USB-CAN card, the fuel cell software part comprises computer software and fuel cell controller software, and a data storage unit is arranged in the fuel cell controller software; a computer controls dynamic loading, air path conditions and target change amplitude of a fuel cell system, and an optimal value is obtained through comparison and is stored as calibration data, so that calibration parameters can be more accurate; the computer records the conditions of all steady-state points, the computer automatically compares the electric pile performance under all the conditions after static work is f
