Performance of microtubular Solid Oxide Fuell Cells for the design and manufacture of a fifty watts stack

Trabajo presentado al 10th European Solid Oxide Fuell Cell Forum celebrado en Lucerna (Suiza) del 26 al 29 de Junio de 2012.Microtubular SOFC cells can support faster warm up time and have higher volumetric energy density compared to tubular, also the mainadvantage of tubular against planar is the facility they present in the sealing. In this work, anode supported microtubular cells have been produed, analyzed and chracterized. The integration feasibility of the stack in a portable power module has been demostrated by the conceptual design of the system. An energy balance has been simulated with Matlab Simulink. The operation modes, efficiency and convection inside the stack have been studied via the Simulink simulation. This model will be validated with the fabrication of an experimental microtubular cell stack. At the moment, an experimental 2 cell-stack has been built and tested with a total power of 0.9W.We would like to thank grants MAT-2009-14324-C02-01, MAT2009-14324-C02-02 and EVIDOS, financed by Spanish Government and Feder program of the European Community for funding the project.Peer Reviewe
