Batteries and Fuel Cells

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...

Electrochemical Cells

Electrochemical Cells

Electrochemical cells are systems that convert chemical energy into electrical energy or use electrical energy to drive chemical reactions. They consist of two electrodes in contact with an electrolyte, where redox reactions enable electron transfer. Most electrochemical cells include two half-cells connected by an external wire for electron flow and a salt bridge for ion flow. The salt bridge contains an electrolyte solution and maintains charge neutrality by allowing ions—not electrons—to...

Background:

Protonic ceramic electrochemical cells (PCCs) are promising for energy conversion but face fabrication and scalability challenges.
Complex manufacturing processes and limited scalability hinder the practical application of PCCs.

Purpose of the Study:

To develop a powder-to-cell engineering strategy linking electrolyte precursor design to cell performance.
To improve the densification, stability, and proton transport of PCC electrolytes.
To enable scalable and cost-effective fabrication of high-performance PCCs.

Main Methods:

Engineered a hybrid-scale BaCe_0.7Zr_0.1Y_0.1Yb_0.1O_3-δ (BCZYYb) precursor integrating microscale and nanoscale components.
Utilized reaction-assisted sintering for improved electrolyte densification and suppressed cation segregation.
Employed cost-effective ceramic processing techniques like tape casting, lamination, and co-sintering for large-area cell fabrication.

Main Results:

Cells from hybrid-scale precursors showed ~60% higher power densities compared to nanoscale precursors.
Achieved kilogram-scale synthesis of the hybrid-scale powder, compatible with industrial ceramic processing.
Demonstrated high electrochemical performance and stable steam electrolysis operation at 1 A cm^-2 with low degradation (0.8% kh^-1).

Conclusions:

The hybrid-scale powder approach significantly enhances PCC performance and addresses scalability limitations.
This strategy facilitates the cost-effective production of large-area PCCs for energy applications.
The developed PCCs show potential for efficient and stable electricity-hydrogen interconversion.
