摘要

制备了微管阳极支撑固体氧化物燃料电池(lt-SOFC)，金属线圈嵌入阳极作为集流器。通过对比不同匝数单位长度和不同成分(镍和钯)的嵌入式线圈的功率密度(PD)，实验考察了其电化学性能。结果表明，单位长度匝数的增加会导致电流密度成比例的增加和PD的二次增量。由于具有更高的氢氧化催化活性，发现具有钯集流器的电池具有额外的性能改进。[DOI: 10.1115/1.4029875]关键词:集流器，阳极负载SOFC，微管SOFC，电化学性能

Effect of the Current Collector on Performance of Anode-Supported Microtubular Solid Oxide Fuel Cells

Microtubular anode-supported solid oxide fuel cells (lt-SOFC) were created with ametallic coil embedded in the anode to act as current collector. The electrochemical per-formance was experimentally examined by comparing the power density (PD) oflt-SOFC with embedded coils of different turns per unit length and composition (nickeland palladium). It is shown that an increase in the turns per unit length results in a pro-portional current density increase and in a quadratic increment of PD. Additional per-formance improvement is found for the cell with palladium current collector due to thehigher catalytic activity for hydrogen oxidation.
