Objective
DEVELOPMENT OF FABRICATION TECHNIQUES FOR MEMBRANES AND THIN ELECTROLYTE AND ELECTRODE LAYERS TO BE APPLIED IN SOFC TECHNOLOGY WITH THE AIM TO IMPROVE EFFICIENCY, TO LOWER POLARIZATION LOSSES, AND TO ALLOW OPERATION OF SOFC AT 800 - 850 CELSIUS DEGREES WITH CURRENT DENSITIES OF 100 - 150 MA/CM TO THE POWER OF 2.
1. STUDY AND DEVELOPMENT OF FLAT PLATE SUPPORT/AIR ELECTRODE COMPOSITES OF STATE OF THE ART MATERIALS (YTTRIA STABILIZED ZIRCONIA AND PEROVSKITES).
2. STUDY, DEVELOPMENT, FABRICATION AND INTEGRATION WITH THE SUPPORTED AIR ELECTRODE OF MEMBRANES AS A BASIS FOR VERY THIN ELECTROLYTE STRUCTURES OF YTTRIA STABILIZED ZIRCONIA (ZY).
3. STUDY AND DEVELOPMENT OF THE CVD/ECVD+ TECHNIQUE FOR THE APPLICATION OF A THIN ZY ELECTROLYTE STRUCTURE (30 - 50 MICROMETERS) ON THE SUPPORTED AIR ELECTRODE COMPOSITE WITH MEMBRANE PROPERTIES. IT WILL BE PURSUED TO APPLY TETRAGONAL ZY COMPOSITIONS WHICH ARE MECHANICALLY TOUGH, AS VERY THIN ELECTROLYTE LAYER INSTEAD OF THE MECHANICALLY BRITTLE CUBIC ZY COMPOSITIONS.
4. CHARACTERIZATION OF MICROSTRUCTURE, ELECTRICAL AND ELECTROCHEMICAL PROPERTIES OF (I) THE SUPPORTED AIR ELECTRODE AND (II) OF THE SUPPORTED AIR ELECTRODE ONTO WHICH THE VERY THIN ELECTROLYTE LAYER OF ZY IS GROWN BY CVD AND ECVD.
5. INTERACTIONS OF FUEL ELECTRODE MATERIALS WITH VERY THIN ELECTROLYTE STRUCTURES.
THIS WORK PROGRAMME WILL BE CARRIED OUT IN STRONG COOPERATION WITH THE DUTCH ENERGY CENTRE (ENC) AT PETTEN (THE NETHERLANDS).
