挤出成型法制备阳极支撑型固体氧化物燃料电池
Tubular Anode-Supported Solid Oxide Fuel Cells by Extrusion Method
摘要
Abstract
Anode-supported solid oxide fuel cells were fabricated by an extrusion method with corn powder, starch and graphite as a pore formation agent, respectively. The YSZ electrolyte layer was dip-coated on a NiO-YSZ anode substrate. The LSM cathode was prepared by a slurry method. The single cell was examined with humidified hydrogen as fuel and air as oxidant at 600-800 ℃. The microstructure of the anode substrates was analyzed by scanning electron microscope. The results show that well-distributed porous anode is obtained after sintered with graphite as a pore formation agent, and the corresponding cells give the superior performance, compared to the cells with other pore formation agents. The maximum power density of a single cell with graphite as a pore formation agent reached 241 mW/cm2 at 800 ℃, and the Ohmic impedance was 0.7 Ω·cm2.关键词
