“…Te merits of an alkaline fuel stack network are moderate efciency, very simple heat management, moderate startup time, high chemical activity, and less expensive anode and cathode materials. In addition, the internal combustion of an alkaline network is easy when equated with the battery system [23]. As a result, the fuel stack takes less money for power supplying to the global industries.…”

At present, there are different types of Renewable Energy Resources (RESs) available in nature which are wind, tidal, fuel cell, and solar. The wind, tidal, and solar power systems give discontinuous power supply which is not suitable for the present automotive systems. Here, the Proton Exchange Membrane Fuel Stack (PEMFS) is used for supplying the power to the electrical vehicle systems. The features of fuel stack networks are very quick static response, plus low atmospheric pollution. Also, this type of power supply system consists of high flexibility and more reliability. However, the fuel stack drawback is a nonlinear power supply nature. As a result, the functioning point of the fuel stack varies from one position to another position on the V-I curve of the fuel stack. Here, the first objective of the work is the development of the Grey Wolf Optimization Technique (GWOT) involving a Fuzzy Logic Controller (FLC) for finding the Maximum Power Point (MPP) of the fuel stack. This hybrid GWOT-FLC controller stabilizes the source power under various operating temperature conditions of the fuel stack. However, the fuel stack supplies very little output voltage which is improved by introducing the Single Switch Universal Supply Voltage Boost Converter (SSUSVBC) in the second objective. The features of this proposed DC-DC converter are fewer voltage distortions of the fuel stack output voltage, high voltage conversion ratio, and low-level voltage stress on switches. The fuel stack integrated SSUSVBC is analyzed by selecting the MATLAB/Simulink window. Also, the proposed DC-DC converter is tested by utilizing the programmable DC source.

“…By designing different anode flow channels, the stacking method of Zn particles was changed to improve the discharge efficiency of the cell [10], therefore, reaching the record of the best efficiency value in the scientific research literature. The performance of ZAFC based on the anode fuel of Zn plate and particle was compared [11], indicating that Zn particle coupling with flowing electrolyte has significantly enhanced the performance in terms of opencircuit voltage, power, and current density; Nyquist and Bode's plots also showed better resistance reduction of particle type compared to that of plate type. Flowing electrolyte is a decisive factor that contributes to the continuous fuel supply and brings considerable benefits to this kind of cell.…”

The flowing electrolyte in a zinc-air fuel cell (ZAFC) can reduce the problem of incomplete reaction caused by the concentration gradient of the electrolyte. In this study, we propose a self-developed ZAFC with a flowing electrolyte system and optimize control parameters. The anode of the ZAFC used Zn particles through which the electrolyte penetrates and combined with a negative pressure pump to allow the potassium hydroxide (KOH) electrolyte to have an effective chemical reaction with the Zn particles during the discharge process. However, the flow rate of the electrolyte is required to match other control parameters, such as operating temperature, KOH concentration, and cell size, to effectively improve the efficiency of ZAFC. Therefore, the Taguchi method is adopted to obtain the optimal reaction parameters and the key factors affecting the discharge efficiency of the cell. The best operation condition is the temperature at 50°C, the KOH concentration of 30% wt, and the electrolyte flow rate of 150ml/min; then, the maximum power obtained from the experimental results is 13.8 W, the maximum current density reaches 699.721 mA/cm2, and the maximum power density is 395.037 mW/cm2. This paper provides valuable insights for the upgrade of ZAFC for future practical applications.
