Low‐operating‐temperature solid oxide fuel cells (LT‐SOFCs) with various kinds of fuel, such as hydrocarbons, biogas, natural gas, and oxygenated fuel has been an active SOFC research topic. However, conventional SOFC anodes comprised of nickel metal and yttria‐stabilized zirconia composite (Ni‐YSZ) experience rapid degradation when operated for the butane direct internal steam reforming (B‐DISR), especially at a low temperature (LT) range. This study reveals that the impregnated Pd into the Ni‐YSZ anode support of thin‐film SOFCs (TF‐SOFCs) is effective for achieving better performance and stability regarding the TF‐SOFC in B‐DISR at 600°C. Adding Pd as a dopant into Ni‐YSZ significantly promotes the catalytic activity due to the Pd‐Ni alloy formation, both on the YSZ grain and the Ni grain surface. The electrochemical performance of cells without Pd (Ni‐YSZ cell) and a Pd‐infiltrated Ni‐YSZ anode (Pd‐Ni‐YSZ cell) are compared at 600°C for the B‐DISR mode at a ratio of steam‐to‐carbon of 3. Finally, long‐term durability tests were performed at 600°C and under 0.15 A cm⁻². The Pd infiltration decreases the deterioration rate to 0.63 mV h⁻¹ after the first 80 hours of operation for the Pd‐Ni‐YSZ cell, which was a significant improvement from that of the Ni‐YSZ cell, 3.75 mV h⁻¹ after 40 hours of operation.

通过钯渗透提高丁烷操作的低温固体氧化物燃料电池的电化学性能和耐久性

SOFC的研究主题是使用各种燃料（例如碳氢化合物，沼气，天然气和含氧燃料）的低温工作的固体氧化物燃料电池（LT-SOFC）。但是，常规的由镍金属和氧化钇稳定的氧化锆复合材料（Ni-YSZ）组成的SOFC阳极在进行丁烷直接内部蒸汽重整（B-DISR）时，尤其是在低温（LT）范围内运行时，会迅速降解。这项研究表明，在600°C下，B-DISR中的TF-SOFC在TF-SOFC的Ni-YSZ薄膜载体的Ni-YSZ阳极载体中的浸渍钯是有效的。由于在YSZ晶粒和Ni晶粒表面都形成了Pd-Ni合金，因此将Pd作为掺杂剂添加到Ni-YSZ中可显着提高催化活性。⁻²。Pd-Ni-YSZ电池运行后的最初80小时后，Pd渗透将劣化率降低到0.63 mV h ^-1，这比Ni-YSZ电池运行40小时后的3.75 mV h ^-1显着改善营业时间。
