In the present work, a hydroelectric cell (HEC) is fabricated to generate the electricity through the splitting of water into H₃O⁺ and OH⁻ ions without releasing any toxic by-product. Nanoporous Fe₃O₄ and Li-doped Fe₃O₄ materials have been synthesized by facile chemical co-precipitation method. BET (Brunauer–Emmett–Teller theory) results exhibited surface area of Li-doped Fe₃O₄ to be 45 m²/g with pore radius ∼4 nm. The obtained powder was pressed into pellets of 4.08 cm² area. Then, Zn electrode was attached at one face of each pellet and silver on the opposite face to fabricate the hydroelectric cells. Cyclic Voltammetry (CV) curve of HEC demonstrates cathodic and anodic peak corresponding to a redox reaction at Zn and silver electrodes. The fabricated HEC of 4.08 cm² area of Li-doped Fe₃O₄ delivers short circuit current, open-circuit voltage and off-load output power as 44.91 mA, 0.68 V, 30.80 mW, respectively. Ionic diffusion of the dissociated H₃O⁺ and OH⁻ ions have been confirmed by Nyquist curves of both HEC’s compared to a dry state. The off-load 30.80 mW output power generation through Li-doped Fe₃O₄ based Hydroelectric Cell of 4.08 cm² area is significant and has emerged as a viable alternative to other green energy sources.
