Development of hybrid aluminum-air battery fuel-cell system

Abstract Industrial 4.0 accelerates the need to introduce clean energy accommodate increase in electricity demand globally without causing environmental issues. Metal-air battery is a new type of storage system which metal anode consumed generate through electrochemical reaction. Among various types anode, aluminum promising carrier. Aluminum-air shows advantages such as high capacity, abundance, low cost, and being environmentally friendly. Traditional aqueous aluminum-air experiences restriction from application due its self-corrosion In this study, instead reducing or limiting issues, different approach proposed so make use issues battery. By incorporating an additional hydrogen-air subcell battery, hybrid turned issue into beneficial reaction by utilizing hydrogen gas produced fuel power cell improving overall performance. The electrical performance each studied experimentally using potassium hydroxide electrolytes. great improvement compared single system. maximum improved more than 40%. This study that design feasible enhancing yet, maintaining cost weight nature.
