PURPOSE:To prevent electrolyte solution from high concentration by housing a power generation elemental body in a battery jar made of synthetic resin containing a filler having little steam permeability for relaxing decrease of moisture in the electrolyte solution by the filler. CONSTITUTION:Flat material, for instance, microglass flakes or the like having completely or nearly no steam permeability as a simple substance is used as a filler. In said action, the flatness of the filler makes it to form a filler layer nearly monoblock wall while the flat surfaces are continuously arranged in a row along the flow of resin at the time of molding. Said filler layer takes the form to cover the greater part of the surface area of a battery jar. Moreover, the extremely low steam permeability of the filler checks penetration of the steam from the wall of the battery jar, whereby preventing electrolyte solution from high concentration. |
