Researchers design iron-based cathode to achieve record performance for protonic ceramic fuel cells

https://techxplore.com/news/2022-11-iron-based-cathode-protonic-ceramic-fuel.html

"cathode materials from basic physical-chemical principles and density functional theory... Ba0.875Fe0.875Zr0.125O3-δ (D-BFZ) promising cathode material... D-BFZ has an exceptional electrochemical activity to react with oxygen... high peak power density and excellent operational stability. Moreover, D-BFZ can be produced using simple, mass-production-suitable synthesis techniques, which is a major step toward realizing commercially viable protonic ceramic fuel cells"
