Solid oxide fuel cell (SOFC) systems allow efficient direct conversion from chemical to electrical energy. But the commercialization of the technology is strongly dependent on the development of cost-effective, long-term stable materials and seals. Sealing components in SOFC stacks have to fulfill a large variety of requirements. Primarily, they should separate the oxidants and fuel gases under all operating conditions, e.g. thermal cycling, rapid heating/cooling, temperature gradients. In this article, the state-of-the-art knowledge in SOFC sealing technology is described for the two main development directions—glass sealants and compressive sealants
- compressive sealants;
- glass sealants;
- ceramic sealants;
- metal sealants;
- mica sealants
