Controlling a Fuel Cell Group in an Electric Vehicle via Grouping Start-Stop Method

Abstract
This research presents a method for controlling a fuel cell group in an electric vehicle. The method involves dividing a high-power fuel cell stack into multiple small-power fuel cell stacks and starting and stopping them in a grouping manner during the vehicle's operation. The small-power fuel cell stacks are started based on the vehicle's running state and stopped based on the performance degradation of each individual stack. The proposed method improves the efficiency and fuel economy of the power system, reduces performance degradation of fuel cells, extends the service life of the fuel cell power system, and provides significant practical value.
