Description
The project focuses on the development of a novel, industrially scalable, electrolyte-supported fuel cell and its development to prototype maturity. The aim of the project is to systematically investigate robust titanate materials as catalytically active anode current collectors and implement them into a proven electrolyte-supported fuel cell microstructure. This new anode microstructure should be compatible with ferritic interconnectors and, in contrast to current cell technology, significantly more tolerant to overload and fuel contamination. Successful engineering implementation is achieved by combining latest findings from materials science with modern methods of materials modelling and microstructure analysis. This approach enables to define appropriate design recommendations for material-microstructure-performance correlations and to realize them for practical application.
