| 摘要 |
The present invention relates to a sealant for a low temperature operation solid oxide fuel cell and a manufacturing method thereof and, more specifically, to a sealant for plate-shaped solid oxide fuel cell stack which is operated at low operation temperatures of 700°C or less. The composite sealant according to the present invention exhibits excellent compression resistance and long term endurance at 700 °C, prevents a softening point from being increased while maintaining low nucleation rate, maintains stable states and has excellent thermal cycle sealing stability since leakage and deterioration are not generated, thereby being able to be usefully used as a sealant for a low temperature plate-shaped solid oxide fuel cell stack and being able to usefully used in a plate-shaped solid oxide fuel cell stack module, a plate-shaped solid oxide fuel cell system, a plate-shaped solid oxide fuel cell single cell including the composite sealant of the present invention and the like. |
