固体氧化物燃料电池（SOFC）被提议用于热电联用，但启动缓慢，循环有限。在这项工作中，对住宅式加热炉的换热器进行了改造，并在燃烧过程中集成了SOFC烟囱。具体来说，SOFC通过电化学氧化燃烧废气中的剩余燃料来发电。SOFC烟囱是热循环的，因为住宅式加热炉经历了200次开/关循环。实现了215°C/min的快速启动速率和205°C/min的快速冷却速率。电堆产生的高功率密度超过150 mW/cm2。 引用:2019年年度会议，密苏里州堪萨斯城，扩展摘要

Solid Oxide Fuel Cells (SOFCs) have been proposed for Combined Heat and Power applications, but suffer from slow startup and limited cycling. In this work the heat exchanger of a residential furnace is modified and a SOFC stack is integrated in the combustion process. Specifically, the SOFC generates electricity by electrochemically oxidizing remaining fuel in the combustion exhaust. The SOFC stack is thermal cycled as the residential furnace undergoes 200 on/off cycles. A rapid startup rate of 215°C/min and a rapid cool down rate of 205°C/min are achieved. The stack produces a high power density exceeding 150 mW/cm2.
