Evolved materials and innovative design for high-performance, durable and reliable SOFC cell and stack

Evolve focuses on an innovative concept for SOFC, particularly for the anode compartment, enable cell operation at reduced temperature of 750 °C. Targeting the full removal and or replacement of Nickel as electrocatalysts at the anode side by electronic conducting ceramic oxides,this concept is expected to enhance the durability and reliability of SOFC while exhibiting performance level comparable to main-stream anode-supported cells. It is thus targeted:
-to reduce the amount of Nickel in the current collector
-to replace Nickel within the Anode Functional Layer by the a composite LST-CGO modified by catalysts: Co/Fe-Pd or alternatively Rh-CGO and Ru-CGO.
The main objectives of EVOLVE are:
- the demonstration at the stack level of a SOFC implementing an innovative substrate resilient toward redox cycles with higher durability than mainstreams Metal Supported Cells implementing porous ferritic stainless steel substrates and cyclability than mainstreams anode supported cells implementing the Ni based cermet.
- the identification of innovative combinations of advanced materials with reduced amount of nickel, showing improved tolerance against Sulfur poisoning compared to mainstreams nickel based cermet Anode and higher resilience against redox cycles.
