Description
Summary:This study establishes a simulation model of the voltage output of a fuel cell stack based on its basic design parameters. Under the condition that the number of cells in the stack remains unchanged, the output capacity of the stack from the control level is explored to increase the power level. This study optimizes the system, analyzes the game process between the parasitic power supply system and the output power of the fuel cell stack, and optimizes the output capacity of the fuel cell stack by compensating the backpressure. To strengthen the flow-pressure coupling during pressure compensation, the principle of auto-disturbance decoupling control is applied to the strong coupling system to design a flow-pressure dynamic decoupling controller that can weaken the flow-pressure coupling effect.
