چکیده انگلیسی
In this study, a proton conducting solid oxide fuel cell (layered H+-SOFC) is prepared by introducing a La2NiO4perovskite oxide with a Ruddlesden-Popper structure as a catalyst layer onto a conventional NiO + BaZr0.4Ce0.4Y0.2O3-δ (NiO + BZCY4) anode for in situ CO2 dry reforming of methane. The roles of the La2NiO4 catalyst layer on the reforming activity, coking tolerance, electrocatalytic activity and operational stability of the anodes are systematically studied. The La2NiO4 catalyst layer exhibits greater catalytic performance than the NiO + BZCY4 anode during the CO2 dry reforming of methane. An outstanding coking resistance capability is also demonstrated. The layered H+-SOFC consumes H2 produced in situ at the anode and delivers a much higher power output than the conventional cell with the NiO + BZCY4 anode. The improved coking resistance of the layered H+-SOFC results in a steady output voltage of â¼0.6 V under a constant current density of 200 mA cmâ2. In summary, the H+-SOFC with La2NiO4 perovskite oxide is a potential energy conversion device for CO2 conversion and utilization with co-generation of electricity and syngas.
