Abstract

The invention discloses a control method and device of a fuel cell. The method comprises the steps that a first state variable and a first control variable of a target fuel cell are obtained, the first state variable is a variable of the current state of the target fuel cell, and the first control variable is a variable for controlling the state of the target fuel cell; constructing a target optimization function based on the first state variable and the first control variable; and updating the first control variable based on the target optimization function to obtain a target control variable which is used for controlling the target current and the target duty ratio of the target fuel cell. According to the invention, the technical problem of low vehicle performance caused by poor control effect of the control method of the fuel cell in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of automobiles, and in particular, to a control method and device for a fuel cell. Background technique [0002] At present, for fuel cell vehicles, the temperature of the fuel cell is too high or too low, which has a great impact on the performance of the whole vehicle. If the temperature is too high, the proton membrane will be dehydrated, the conductivity will be reduced, and the proton exchange membrane will be damaged. low, it will cause the output power of the fuel cell to decrease. However, most of the control strategies of fuel cell vehicles are single vehicle energy management. Only from the perspective of power system energy flow, the output power of fuel cells is controlled to achieve economy, resulting in poor control effect and low vehicle performance. [0003] For the above problems, no effective solution has been proposed yet. SUMMARY OF THE INVENTION [0004] Embodiments of the present inve...
