Types of Reversible Electrodes01:24

Types of Reversible Electrodes

For electrode reversibility to be maintained, all the reactants and products involved in the half-reaction must be present at the electrode. There are several types of reversible electrodes (half-cells).In metal-metal-ion electrodes, a metal balances electrochemically with a solution of its own ions. Examples are Cu2+|Cu and Zn2+|Zn. Metals that react with the solvent, like group 1 and most group 2 metals, which react with water, and zinc, which reacts with aqueous acidic solutions, cannot be...
The Electrical Double Layer01:30

The Electrical Double Layer

In the region where two bulk phases meet, an intricate electric charge distribution arises due to charge transfer, ion adsorption, molecular orientation, and charge distortion. This complex distribution is commonly referred to as the electrical double layer.When a solid electrode interfaces with ions in an electrolyte solution, the speed of electron transfer dictates the rates of oxidation and reduction. The electrode acquires a charge through the escape of atoms into the solution as cations or...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Conversion

Background:

  • Protonic ceramic fuel cells (PCFCs) require active and durable cathode materials for efficient oxygen reduction reaction (ORR).
  • Perovskite oxides with mixed conductivity are promising but degrade in CO2 environments due to alkaline earth elements.

Purpose of the Study:

  • To develop a novel approach for enhancing PCFC cathode performance and CO2 resistance.
  • To engineer cathode surface and bulk properties separately using in situ phase segregation.

Main Methods:

  • Co-incorporation of Li+ and K+ into a model BaCo0.4Fe0.4Zr0.1Y0.1O3-δ cathode.
  • Targeted control of cation size mismatch to induce selective in situ phase segregation.
  • Evaluation of the restructured cathode's performance and CO2 tolerance at 600 °C.

Main Results:

  • Li+ segregated to the surface, providing CO2 resistance, while K+ remained in the bulk, enhancing proton transport.
  • The in situ restructured cathode demonstrated a 30% increase in PCFC power output.
  • CO2 tolerance was improved fivefold in the presence of CO2 at 600 °C.

Conclusions:

  • Selective in situ phase segregation is an effective strategy for designing advanced PCFC cathode materials.
  • The engineered cathode offers a pathway to overcome CO2 degradation issues, improving PCFC durability and efficiency.
