Abstract
A cell case is provided which maintains cell temperature low by reducing heat reception during no power generation, while ensuring heat dissipation performance during generating power, and which is capable of suppressing reduction of cell capacity due to thermal degradation. A structure for attaching the cell case is also provided. The cell case has a sealed structure and houses a battery module. The cell case has a supporting mechanism which forms a space between the outer surface of the battery module and the inner surface of the case. A first cover layer has a radiation emissivity larger than that of the outer surface of the battery module and is disposed on the outer surface of the cell module. A second cover layer has a radiation emissivity larger than that of the inner surface of the case and is disposed on the inner surface of the case.
