Batteries and Fuel Cells

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
Energy Conversion

Background:

Protonic ceramic fuel cells (PCFCs) are promising for sustainable energy.
Sluggish cathode kinetics and poor stability limit PCFC performance.
Developing advanced cathode materials is crucial for PCFC commercialization.

Purpose of the Study:

To develop a facile and efficient method to improve PCFC cathode performance and stability.
To engineer the surface chemistry of PrBa0.5Sr0.5Co1.5Fe0.5O5+δ (PBSCF) cathodes.
To investigate the impact of surface modification on the oxygen reduction reaction kinetics and durability.

Main Methods:

Utilized a reverse atom capture technique to modify the PBSCF cathode surface.
Introduced W species to capture segregated Ba and Sr cations, forming a (Ba/Sr)(Co/Fe/W)O3-δ (BSCFW)@PBSCF heterostructure.
Fabricated and tested single PCFC cells with the modified cathode.

Main Results:

The optimized 2W-PBSCF cathode achieved a peak power density of 1.32 W cm⁻² at 650 °C.
The modified cathode demonstrated durable performance, maintaining stability for 240 hours.
Theoretical calculations confirmed improved oxygen vacancy formation, hydration, and proton transfer energies in the BSCFW perovskite.

Conclusions:

The reverse atom capture technique effectively enhances PCFC cathode performance and durability.
The BSCFW@PBSCF heterostructure offers superior kinetics and stability for proton-involved reactions.
This approach provides new strategies for designing advanced cathode materials for sustainable energy applications.
