The deformation of a plate-like member (a separator) or the degradation of a seal function due to heat generated during power generation is suppressed. To realize this, disclosed is a heat insulation cell for a fuel cell in which an insulation layer is constituted of one or more plate-like members and a seal member, the heat insulation cell being provided with a communication section which is disposed in at least a part of a seal line formed by the seal member to seal the insulation layer and the outside of the cell and which connects the insulation layer to the outside. A portion provided with the communication section in at least one of the plate-like members preferably has a projection. It is also preferable that the insulation layer is formed by an insulation member and that the insulation member is disposed in the communication section.
