INTERMEDIATE TEMPERATURE SOLID OXIDE FUEL CELL PERFORMANCE OPTIMISATION

The performances of anode-supported Intermediate Temperature-Solid Oxide Fuel Cells (IT-SOFC), obtained by tape casting, are investigated. The tested cells are composed of four layers: cathode, electrolyte, anode and Anode Functional Layer (AFL). The AFL has to ensure mechanical compatibility between anode and electrolyte and to increase the output power. First performance tests are conducted in the 500 degrees C - 600 degrees C temperature range to determine the maximum power density. In a second time, other parameters are investigated: cathode and electrolyte thickness. For each modification, the performance, in terms of power density, is measured. These results lead to the production of optimised cells which are used to realise long term ageing tests under working conditions. First reactivity results are then discussed.
