PROBLEM TO BE SOLVED: To provide a cooling liquid housing container for a fuel cell which has a rise suppression effect of electric conductivity of the cooling liquid for the fuel cell after storage and which is capable of maintaining the electric conductivity at an initial stage, and also to provide a method for storing the cooling liquid for the fuel cell using the same.SOLUTION: A cooling liquid housing container 1E for a fuel cell includes: an inner layer 11 composed of a polyester resin: a metal layer 12 composed of aluminum provided on the external surface of the inner layer 11; and an outer layer 13 composed of a polyolefin resin on the outside of the metal layer 12. In a method for storing the cooling liquid for the fuel cell, the cooling liquid housing container for the fuel cell houses the cooling liquid for the fuel cell which contains water and glycols and/or alcohols.SELECTED DRAWING: Figure 5 【課題】保管後の燃料電池用冷却液の電気伝導率の上昇抑制効果を有し、初期の電気伝導率を維持できる燃料電池用冷却液収容容器及びそれを用いた燃料電池用冷却液の保管方法を提供する。【解決手段】本発明の燃料電池用冷却液収容容器１Ｅは、ポリエステル樹脂で構成される内層１１と、該内層１１の外側表面に設けられたアルミで構成される金属層１２と、該金属層１２の外側に、更にポリオレフィン樹脂で構成される他の外層１３を有する。本発明の燃料電池用冷却液の保管方法は、本発明の燃料電池用冷却液収容容器に、水とグリコール類及び／又はアルコール類とを含有する燃料電池用冷却液を収容する。【選択図】図５
