与平面燃料电池相比，微管式固体氧化物燃料电池(SOFC)系统具有许多理想的特性，但要实现成功和经济可行的制造工艺和电堆设计，必须克服许多障碍和困难。阳极支撑管为单个电池提供了一个很好的平台。它们允许将有助于最小化极化损失的薄电解液层施加到管的外部，从而避免了在电解液或阴极支撑的管的内部涂覆的困难，或者如果阳极在管的外部则具有燃料室的电堆设计问题。本文描述了由镍和氧化钇稳定的氧化锆(Ni-YSZ)制成的支撑阳极管的制造，在薄的YSZ电解液和薄的一层锰酸锶/钴(LSM)阴极上涂覆一层，然后使用铜焊技术将成品管堆叠在一起，以满足特定的电流/电压要求。描述了单电池的输出特性，以及小电堆(100W，设计功率输出)的特点和主要问题。(C)2005年爱思唯尔B.V.版权所有。
Micro-tubular solid oxide fuel cells (SOFC) systems have many desirable characteristics compared to their planar counter-parts, however there are many obstacles and difficulties that must be met to achieve a successful and economically viable manufacturing process and stack design. Anode supported tubes provide an excellent platform for individual cells. They allow for a thin electrolyte layer, which helps to minimize polarization losses, to be applied to the outside of the tube, thus avoiding the difficulty of coating the inside of an electrolyte or cathode supported tubes, or the stack design problem of having a fuel chamber if the anode is on the outside of the tube.This paper describes the fabrication of supporting anode tubes made of nickel and yttria stabilized zirconia (Ni-YSZ), coated with a thin YSZ electrolyte and a thin coat of lanthanum strontium manganite/cobaltite (LSM) cathode.The finished tubes were then stacked in an array to provide the specific current/voltage requirements, using a brazing technique. A description of the output characteristics of the single cell, and the characteristics and main issues of a small stack (of 100 W, designed power output) are also given. (c) 2005 Elsevier B.V..
