| 520 | _ | _ | |a CaFe3O5 is a promising material for repeated redox cycles at high temperatures due to its remarkable resistance against microstructural degradation. Therefore, it could be used as an oxygen carrier in the partial oxidation or full combustion of hydrocarbons and a subsequent water-gas-shift reaction for the production of hydrogen in a chemical looping process [1]. Also, it is a major candidate material for the internal energy storage in solid oxide cells. Therein, the material acts as a reversible storage for oxygen ions and thus buffers the surrounding atmosphere (H2O/H2) by compensating local changes in the gas composition. Like this, expenses related to gas handling, metering, and storing can be saved. The thermodynamic properties of this phase are calculated and compared to experimentally gathered kinetic results, achieved via repeated redox cycling at 800 °C in a H2O/H2 atmosphere. The microstructural stability is shown via SEM and the phase composition is measured with XRD. A modeling approach is used to predict the interaction of the solid phase with the surrounding gas. Finally, the material is applied in a fuel cell – electrolyzer system, where the redox activity of the material can be measured and analyzed using the time-voltage-current plot. As a result, the accuracy of the phase diagram could be verified, the stability of the microstructure could be proved, and thus a proof-of-concept was established. |
