| 概要 |
Solid oxide fuel cells (SOFCs) are a promising solution to a sustainable energy future. However, cell performance and stability remain a challenge. Durable, nanostructured electrodes fabricated via a ...simple, cost-effective method are an effective way to address these problems. In this work, both the nanostructured PrBa_<0.5>Sr_<0.5>Co_<1.5>Fe_<0.5>O_<5+δ> (PBSCF) cathode and Ni–Ce_<0.8>Sm_<0.2>O_<1.9> (SDC) anode are fabricated on a porous yttria-stabilized zirconia (YSZ) backbone via solution infiltration. Symmetrical cells with a configuration of PBSCF|YSZ|PBSCF show a low interfacial polarization resistance of 0.03 Ω cm^2 with minimal degradation at 700 °C for 600 h. Ni-SDC|YSZ|PBSCF single cells exhibit a peak power density of 0.62 W cm^<-2> at 650 °C operated on H_2 with good thermal cycling stability for 110 h. Single cells also show excellent coking tolerance with stable operation on CH_4 for over 120 h. This work offers a promising pathway toward the development of high-performance and durable SOFCs to be powered by natural gas.続きを見る
