In this modern era, energy devices have become an important part of our daily life. Various types of energy conversion devices have been developed to meet the current energy demands. Semiconductor anode (CdZnO) has been synthesized by the sol-gel method and lattice constants and the band gap results have been compared experimentally and theoretically. XRD results show that Cddoped ZnO shifts the peaks toward the lower angles, increases the lattice parameters, and decreases the crystallite size (48 nm). Microstructure of Cd-doped ZnO shows the agglomerations of particles, found in the shape of cubes, hexagons, and dumbbell shapes with diameter in the range of 2-7 µm. The experimentally obtained conductivity of CdZnO is 0.142 S/cm at 550 • C. The electrochemical impedance spectroscopy shows the decreased resistance with an increase in temperature. The doped system shows a maximum open circuit voltage of 0.95 V and performance of 0.52 W/cm 2 at 550 • C.

“…To eliminate these hindrances, efforts have been made to excavate alternative electrolyte materials with desirable ionic conductivities at reduced temperatures. A composite electrolyte strategy has been proposed based on the assembly of heterogeneous materials, including doped ceria/carbonates, − doped ceria/semiconductor materials, proton conductor/semiconductor materials, , and so forth. The developed composite electrolytes have shown tremendous potential as compared to conventional YSZ or doped ceria-based electrolytes.…”

The excessive consumption of synthesized materials and enhanced environmental protection protocols necessitate the exploitation of desirable functionalities to handle our solid waste. Through a simple calcination and composite strategy, this work envisages the first application of biocalcite derived from the waste of crayfish shells as an electrolyte for solid oxide fuel cells (SOFCs), which demonstrates encouraging performances within a low temperature range of 450−550 °C. The single cell device, assembled from calcined waste shells at 600 °C (CWS600), enables a peak power density of 166 mW cm −2 at 550 °C, and further renders 330 and 256 mW cm −2 after compositing with perovskite La 0.6 Sr 0.4 Co 0.8 Fe 0.2 O 3-δ (LSCF) and layer-structured LiNi 0.8 Co 0.15 Al 0.05 O 2 (LNCA), respectively. Notably, an oxygenion blocking fuel cell is used to confirm the proton-conducting property of CWS600 associated electrolytes. The practical potential of the prepared fuel cells is also validated when the cell voltage of the cell is kept constant value over 10 h during a galvanostatic operation using a CWS600-LSCF electrolyte. These interesting findings may increase the likelihood of transforming our solid municipal waste into electrochemical energy devices, and also importantly, provide an underlying approach for discovering novel electrolytes for low-temperature SOFCs.
