Evolve focuses on an innovative concept for SOFC, particularly for the anode compartment, incorporating advanced materials with an approach in which each material performs only one functionality and enable cell operation at reduced temperature of 750 °C. This concept is expected to enhance the durability and reliability of SOFC while exhibiting performance level equivalent to main-stream anode-supported cells. SOFC cells with innovative anode compartment will be developed reaching following milestone criteria: Power densities of cell at 0.7 V at 750 °C above 550 mW/cm² with hydrogen as fuel gas. Degradation in cell voltage 0.25%, 0.6% and 1.5% per kh during operation with hydrogen as fuel, syngas and syngas with at least 80 ppm of H2S respectively. Tolerance to withstand at least 50 thermal and redox cycles with less than 5% degradation in cell voltage. In the later part, will move from scientific towards pre-industrial development in which objectives are: Demonstrate up-scalability of cells having the performance level defined in objectives 1-3. Integration of cells in 250 W stacks and its operation. Using realistic model cost analysis, establishing processing sequences and practices for the cell components to attain optimal cost-to-quality ratio. The cell will be supported on a novel composite anode-current-collector made of alumina-forming-alloy-foam impregnated with conductive ceramics. An anode layer of LSCM-CGO and YSZ electrolyte will be produced on top of the support followed by sintering. CGO and CGO-LSCF will be deposited on top of electrolyte. Catalysts will be then infiltrated in electrodes. The development will be based on correlating material, processing, microstructure and electrochemical performance and optimizing cell in term of performance and service life by combining experimental work with model for 3D microstructure, electrochemical kinetics and sintering. Based on these optimized processing protocols, up-scaled cell will be stacked.
