FeCr2O4 Nanoparticles as Anode Catalyst for Ethane Proton Conducting Fuel Cell Reactors to Coproduce Ethylene and Electricity

الملخص EN

Ethylene and electrical power are cogenerated in fuel cell reactors with FeCr2O4 nanoparticles as anode catalyst, La0.7Sr0.3FeO3-δ (LSF) as cathode material, and BaCe0.7Zr0.1Y0.2O3-δ (BCZY) perovskite oxide as proton-conducting ceramic electrolyte.

FeCr2O4, BCZY and LSF are synthesized by a sol-gel combustion method.

The power density increases from 70 to 240 mW cm−2, and the ethylene yield increases from about 14.1% to 39.7% when the operating temperature of the proton-conducting fuel cell reactor increases from 650∘C to 750∘C.

The FeCr2O4 anode catalyst exhibits better catalytic performance than nanosized Cr2O3 anode catalyst.
