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. Its output performance is closely related to the operating parameters, such as the reaction gas pressure, flow, humidity, stack operating temperature, load current disturbance, and exhaust interval. Because electrochemical reactions are very sensitive to temperature changes, temperature plays an important role in the efficient and safe operation of PEMFC. PEMFC generates heat in the electrochemical reaction, and the temperature gradually increases with the continuous increase of the output voltage.<br>
