In the presented research; a feasibility study to cover a mobile electrolyte alkaline fuel cell behaviors and characteristics (which the electrolyte has system cooling role) for UPS (Uninterruptable Power Supply) application is provided to use in an energy laboratory. Electrochemical modeling and computations for irreversiblities led to optimization of cell voltage; current & power densities and the results are found to be 0.566V; 574.3 mA/cm2; 325.2 mW/cm2 respectively. By using mentioned quantities; ideal thermodynamic efficiency; real thermodynamic efficiency and electrical efficiency concluded 80%; 38% and 34% respectively. Preliminary electrochemical studies in this research are combined with engineering designs in complementary stage of research. At the next stage; considerations on heat and mass transfer and contributed models lead to approve a double pipe heat exchanger as energy sink. Then the cost model is also determined and the optimization codes are developed to propose best operation point of system with minimizing total cost and determining the heat exchanger dimensions; flow rates and temperatures. Furthermore; parametric analysis for variation of temperature; electrolyte cooling rate and cost of planned AFC has been studied for energy efficiency and performance improvement.
