摘要： PROBLEM TO BE SOLVED: To facilitate conveying operation and to reduce an installation area for a module aggregate by installing a support structural body on the side wall of an adiabatic containers housing a plurality of pieces of high-temperature sodium secondary batteries such as sodium-sulfur batteries. SOLUTION: Because of installation of a support structural body 31, an installation area for a high-temperature sodium secondary battery module may be increased in comparison with that having no support structure 31, however, the support structure 31 is directly installed on the side wall of an adiabatic container 2 and a lateral clearance 40 between a base and the module is eliminated between the support structure 31 and the module, so that the installation area can be greatly reduced as against that for an existing structure module aggregate. A lid is mounted on each adiabatic container 2 for each high- temperature sodium secondary battery module, and the module can be handled independently of each other. Therefore, after a plurality of modules is conveyed to a field, the modules can be laminated so as to be installed by fixing between the support structures 31 together in the field.
