A reactant gas seal is one of critical issues to achieve the reliability of the MCFC stack which is a key equipment in MCFC power plant. The wet-gas seal with carbonate melted at operating temperature (650°C) is generally expected to be suitable for such a seal. We develop the wet seal configuration composed of thin sheet metal parts to be cost-competitive with other power plants. In this report, the proposed configuration of wet-gas seal using thin sheet metal parts is produced for trial, which is assembled in single cells. The leak rates from wet seals were examined under the condition of MCFC operating temperature. Then, the superior seal performance was found and it is confirmed that the wet seal configuration composed of thin sheet is reliable.
