Gas detection apparatus and gas detection method for cell module assemblies
A gas detection apparatus for cell module assemblies accurately and rapidly detects a damaged cell of a cell module assembly and the damaged position of the damaged cell. The gas detection apparatus includes a gas detection chamber configured to receive a cell module assembly; and a sliding die configured to be movable to the lower part of the gas detection chamber in the state in which the cell module assembly is disposed at the upper end thereof. The gas detection apparatus further includes a gas sensor provided in the gas detection chamber, the gas sensor including a plurality of gas sensors disposed so as to correspond to positions of cells of the cell module assembly. A gas detection method for cell module assemblies uses the gas detection apparatus for cell module assemblies.
