Ethylene and electrical power are cogenerated in fuel cell reactors with FeCr2O4 nanoparticles as anode catalyst, L a 0 . 7 S r 0 . 3 F e O 3 - 𝛿 (LSF) as cathode material, and B a C e 0 . 7 Z r 0 . 1 Y 0 . 2 O 3 - 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.
