DK-SOFTC b, long term development
The project was carried out as a part of DK-SOFC 2000 - 20004. The DK-SOFC b line is targeted towards: 1) decrease of the operation temperature without increasing the area specific resistance, 2) increase of the robustness of the cell, 3) better understanding of mechanisms.
The primary target of the Danish solid oxide fuel cell program is to create a possibility for the establishment of a Danish production of highly effective and environmentally friendly electric power generation plants. A strategy has been established for commercialisation of the technology, based on results obtained in preceeding projects and based on a considerable industrial interest. Continuation of previous projects is effected by two project elements. The first, supported by electric utilities, addresses problems associated with the demonstration of Danish cell- and stacking technology. The other part, sponsored by the acceptance of the present EFP2001 proposal, maintains the long term development lines directed towards reduction of operation temperatures without the associated increase in internal resistance, directed towards an increase of the robustness of cells and stacks and directed towards an understanding of relevant mechanisms. The build-up of a base of patents is another important aspect of the project
The planned activities in the EFP 2001 project were: Cell test under extreme conditions, development and analysis of contacting, stability towards redox and thermal cycling, improvements of methods, development of materials and components. The work was carried out approximately as planned. Some significant results are: An anode-supported cell with low internal resistance and good durability at 850 deg. C has been developed. Contacting of ceramics to ceramics and to metallic interconnect was investigated. There are problems in obtaining stable contact. Poisoning of the cathode by chromium oxide was followed over prolonged periods, and also here problems were encountered. The results emphasize the importance of decreasing the operation temperature of SOFC further, down to the range of 550-650 deg. C. New promising materials for electrodes have been synthesized
