Abstract
The invention related to metal-supported solid oxide fuel cells (SOFC), fuel cell stacks containing the same, methods of their manufacture and use thereof. The SOFC of the invention utilizes an extended electrolyte and barrier layers to prevent specific types of corrosion of the metal substrate. This new coating approach reduces the rate of degradation of the fuel cells and improves system reliability when operated over long durations.
