Therefore, in order to minimize the cost of the PEMFC system, how to make the PEMFC achieve the best net power of the system in a short time and stabilize in the best-performing state for a long time has received considerable critical attention [7], [8]. Furthermore, too little work has been devoted to study the influence of the auxiliary machine consumption of PEMFC on the net power of the stack. One of the main obstacles is how to accurately describe the PEMFC to achieve its maximum net PowerPoint. Its working principle involves many fields, such as fluid dynamics, thermodynamics, and electrochemistry.
