Symposium Energy Materials 2017: Materials for Energy Conversion with Emphasis on SOFC
Presentation Title Fabrication and Operation of a 600W Anode-supported Tubular SOFC Stack
Author(s) Zhengguang Yu, Shaorong Wang
On-Site Speaker (Planned) Zhengguang Yu
Abstract Scope A NiO-YSZ anode-supported tubular SOFC stack for high temperature operation was fabricated and operated in this work. For this purpose, we fabricated anode-supported tubular cells with one end closed by casting, dip coating and co-sintering process. After that, the 600W stack was assembled with these prepared tubular cells by connecting in series to 16 bundles, in which one unit bundle consists of three tubular cells connected in parallel. Experimental results show that single cell with an effective electrode area of 70 cm2 was found to give a maximum peak power density of 310mW/cm2 at 850C , Moreover, these cells also exhibit less than 2% degradation after 10 times thermal cycles. However, using a kind of Nickel alloy materials (Hasteloy C-276) as current connector, the performance of the stack in 3% humidified H2 and air at 850 C outputted a maximum electrical power of 588 W (fuel utilization ratio =34%).
