NexTech Materials will demonstrate the applicability of their aluminization process to solid oxide fuel cell (SOFC) applications. Two commercially important systems will be investigated:
Compatibility of aluminide coating with SOFC stack components will be evaluated, including interactions with sealant materials and other cell components. A complete interconnect coating solution will be demonstrated by integrating the aluminide coating with the existing manganese cobalt oxide (MCO) active layer coating. The performance of these dual MCO/aluminide coated interconnects will be validated through three-cell stack tests;
The high-temperature corrosion protection and chromium volatilization mitigation of aluminide coated balance-of-plant (BOP) components will also be evaluated. The commercial potential of the aluminization process for providing protective aluminide coatings for both the non-active seal area of metallic interconnects and BOP components will be quantified based on an analysis of cost and performance. This work leverages NexTech’s process technology for applying conductive oxide protective coatings to ferritic steels and has already been translated from the laboratory to pilot-scale manufacturing.
NexTech Materials builds upon encouraging preliminary results to develop a commercially viable aluminization process that is amenable to high volume SOFC manufacturing. This work will leverage NexTech’s commercial process technology for applying conductive oxide protective coatings to ferritic steels – a process that has already been translated from the laboratory to pilot scale manufacturing at NexTech. It is anticipated that this will expedite commercialization of the aluminization process.
