Partition member

Abstract

The present disclosure provides a partition member that can suppress a reduction in heat-insulating properties. A partition member (1) is interposed between any pair of cells (92) adjacent to each other in a stacking direction in a stack (91) of multiple cells (92). The partition member (1) includes: a heat-insulating layer (2); a spacer layer (5, 5a) interposed between the heat-insulating layer (2) and the cell (92) and made of a material different from that of the heat-insulating layer (2); and a permeation-suppressing layer (6, 6a) interposed between the heat-insulating layer (2) and the spacer layer (5, 5a) and configured to suppress permeation of the material of the spacer layer (5, 5a) into the heat-insulating layer (2).

Dependencies are inferred from the claim text.
