Study on Fabrication and Performance of Metal-supported Solid Oxide Fuel Cells - Yucun Zhou Gebunden

This book highlights the development of novel metal-supported solid oxide fuel cells (MS-SOFCs). It describes the metal-supported solid oxide fuel cells (MS-SOFCs) that consist of a microporous stainless steel support nanoporous electrode composites and a thin ceramic electrolyte using the tape casting-sintering-infiltrating method. Further it investigates the reaction kinetics of the fuel cells' electrodes structure-performance relationship and degradation mechanism. By optimizing the electrode materials preparation process for the fuel cells and nano-micro structure of the electrode th e resulting MS-SOFCs demonstrated (1) great output power densities at low temperatures e.g. 1.02 W cm-2 at 600°C when operating in humidified hydrogen fuels and air oxidants (2) excellent long-term stability e.g. a degradation rate of 1.3% kh-1 when measured at 650°C and 0.9 A cm-2 for 1500 h. The design presented offers a promising pathway for the development of low-cost high power-density and long-term-stable SOFCs for energy conversion.
