“…Under extremely low temperatures, the cell performance was poor as well because of the decrease in the electrolyte ion transport ability. Theoretical substantiation has been provided by Manachi et al, where they have stated that the efficiency of the fuel cells may reduce with temperature rise above the boiling points of the products involved in the chemical reactions as this would in turn intensify the enthalpies of product formation. Higher operational temperatures may also result in increased internal resistance and ohmic losses.…”

Summary A dynamic research endeavor has been performed in this research study by constructing and operating an innovative flowing type anode (zinc gel) along with Carbopol 960 additives as thickener in a zinc‐air fuel cell. This gel constituted of a mixture of Zn powder, thickener, and potassium hydroxide (KOH) electrolyte, and it was fueled into the cell with a peristaltic pump. The flowing Zn anode allowed the reaction‐produced water, carbonate, and zinc oxide (ZnO) to be discharged from the cell. Basic operating parameters of the fuel cell like the concentrations of the Zn powder, thickener, and electrolyte along with the number and grid density of the current collector grid, cell operation temperature, and air flow rate were all optimized for effective and enhanced fuel cell performance. It was determined based on voltage production along with current and energy density generation. The augmented experimental results were as follows; thickener concentration of 1 to 2 wt% was observed to be optimum above which the electrolyte acquired a solid state. The voltage production was stable at electrolyte concentrations of 60 to 65 wt% and Zn powder concentrations lower than 40 wt%, and concentrations greater than this resulted in reduced cell performance. The implementation of four current collector grids each with an opening density of 144 grid/cm2 had efficiently amplified cell performance. The ideal cell temperature was determined to be 40°C, and maximum cell production was attained at an air flow rate of 2 m/s. Consequently, effective improvement and advancement in the processes and operational parameters were achieved in this zinc‐air fuel cell with a state‐of‐the‐art anode fuel. This will surely provide great opportunities for their applications in the future.

“…A study by K. Harding et al [8] investigated and made comparisons on the costs involved and efficiency limits achievable by zinc air batteries, hydrogen cells and solar panels as potential power sources for electric vehicles. Both solar panels and zinc air batteries were found to have the best performance for the intended end use.…”

Presently, Malaysia is fostering growth in the green energy sector in order to reduce its carbon emissions and contribute in the fight against global warming. Renewable Energy (RE) such as solar cell could no longer be considered as a green technology because at the end of their lifecycle, they become non- biodegradable waste which in turn constitutes pollution and contributes to global warming. Thus, the aim of this research is to study a self-sustaining solar module produced by upcycling solar cells from non- biodegradable waste. Several solar cells from electronic devices were reused in this study. The results obtained show that a combination of 4V, 3V and 2V reused solar cells produced 10.20V and 47.9mW of power. This indicates that the proposed upcycled solar module is feasible and has the potential to aid in the promotion of clean and renewable energy use in order to attain the desired sustainable development goals.Keywords: solar module, self-sustaining, solar cell, non-degradable waste
