EVOLVE aims at the development, the up-scaling and the demonstration of new SOFC architecture for mobile applications. This architecture, based on a composite anode substrate that is tolerant towards redox cycles aims at combining the benefits of both existing Anode and Metal supported cell architecture and limiting the issue of carbon coking and sulphur tolerance as a result of improved anode materials.


This concept is expected to offer a performance level comparable to main stream commercial anode supported cells with enhanced robustness and durability. Due to the system’s tolerance toward the redox cycle, coking and sulphur poisoning, the cell design is expected to lead to a simplified and cost-effective balance of plant. The development of a trans-discipline scientific aspect on the basics of material science, processing, electrochemistry, fundamental modelling, and production and system engineering for technological development beyond the SOFC field is also expected.


EVOLVE focuses on an innovative concept for SOFC, particularly for the anode compartment, incorporating advanced materials with an approach in which each material performs a single function and enables cell operation at reduced temperature of 750°C. This concept is expected to enhance the durability and reliability of SOFC while exhibiting performance levels which are equivalent to mainstream anode supported cells. SOFC cells with an innovative anode compartment will be developed, reaching the following milestone criteria:

  • Power densities of cells at 0,7V at 750°C above 550mW/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 80ppm of H2S respectively.
  • Tolerance to withstand at least 50 thermal and redox cycles with less than 5% degradation in cell voltage

In the latter part, the project will move from a scientific basis toward pre-industrial development, in which the objectives are to:

  • Demonstrate the up-scalability of cells having the performance level defined in objectives 1-3
  • Integrate cells in 250W stacks and its operation
  • Use a realistic model of cost analysis, establishing processing sequences and practices for the cell components in order to attain an 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 an electrolyte. Catalysts will be the inserted in the electrodes. The development will be based on correlating material, processing, microstructure and electrochemical performance and cell optimization in term of performance and service life, by combining experimental work with models for a 3D microstructure, electrochemical kinetics and sintering. Based on these optimized processing protocols, up-scaled cells will be stacked.
