An advantage of mixed-metal oxides is the possibility of site-specific metal cation substitution, which can tune the physical and catalytic properties of the material. Ongoing work at ISEE has explored the impact that site-specific substitution has upon the electrocatalyst performance for e-ODH.
Practical implementation of an e-ODH SOFC system requires knowledge about how feed composition will affect the reaction performance. This knowledge would be used to determine if e-ODH would require associated processing steps. To evaluate whether e-ODH would need drying operations, the impact of a humidified versus a dry ethane feedstock will be tested.
This presentation will cover the impact of site-specific metal cation substitution upon the mixed-metal oxide electrocatalysts used for e-ODH and the effects of a humidified versus a dried ethane feed. Chemical and electrochemical testing results and materials characterization will be presented.
