چکیده انگلیسی
Recent development on electrolyte-free fuel cell (EFFC) holding the same function with the traditional solid oxide fuel cell (SOFC) but with a much simpler structure has drawn increasing attention. Herein, we report a composite of industrial grade rare-earth precursor for agriculture and Li0.3Ni0.9Cu0.07Sr0.03O2-δ (RE-LNCS) for EFFCs. Both structural and electrical properties are investigated on the composite. It reveals that the RE-LNCS possesses a comparable ionic and an electronic conductivities, 0.11 S cmâ1 and 0.20 S cmâ1 at 550 °C, respectively. An excellent power output of 1180 mW cmâ2 has been achieved at 550 °C, which is much better than that of the conventional anode/electrolyte/cathode based SOFCs, only around 360 mW cmâ2 by using ionic conducting rare-earth material as the electrolyte. Engineering large size cells with active area of 25 cm2 prepared by tape-casting and hot-pressing gave a power output up to 12 W. This work develops a new functional single layer composite material for EFFCs and further explores the device functions.
