Batteries and Fuel Cells

24.1K
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Solid-State Chemistry

Background:

  • Ceramic fuel cells (CFCs) face high-temperature limitations hindering widespread adoption.
  • Efficient proton transport in electrolytes is crucial for lowering operating temperatures.
  • Existing electrolytes often require high temperatures for adequate ionic conductivity.

Purpose of the Study:

  • To develop a novel electrolyte for low-temperature ceramic fuel cells.
  • To enhance proton conductivity by surface engineering of strontium titanate (SrTiO3-δ).
  • To investigate the mechanism of improved ionic transport at reduced operating temperatures.

Main Methods:

  • Surface engineering of SrTiO3-δ electrolyte with 10 mol%-CeO2 coating, creating a core-shell heterostructure.
  • Characterization of ionic conductivity and electrochemical performance at low temperatures (e.g., 550 °C).
  • Isotopic substitution and proton-blocking membrane experiments to confirm conduction mechanism.
  • Density functional theory (DFT) calculations to elucidate the role of oxygen vacancies and surface structure.

Main Results:

  • The 10 mol%-CeO2-coated SrTiO3-δ electrolyte achieved high ionic conductivity (0.14 S cm-1) at 550 °C.
  • A peak power density of 0.81 W cm-2 was delivered at 550 °C.
  • Protonic conduction was confirmed as the dominant mechanism, contributing up to 78% of the total power output.
  • DFT calculations revealed lowered oxygen vacancy formation energy (3.7 eV) and facilitated proton transport due to the CeO2 coating.

Conclusions:

  • Surface engineering of SrTiO3-δ with CeO2 is a viable strategy for high-performance low-temperature CFC electrolytes.
  • The core-shell heterostructure promotes oxygen vacancies at the interface, enhancing proton migration.
  • This approach offers a scalable and cost-effective alternative to conventional bulk doping methods for improving CFC performance.
