PROBLEM TO BE SOLVED: To provide a tank having two-layer structure to be laid underground which allows replenishment of a fuel to a fuel battery vehicle even in existing gasoline stations by using a solvent-resistant material on the inner side of the laid tank.SOLUTION: A corrosion protection structure of a solvent tank is used in a solvent tank for storing a solvent to be used in a fuel of a fuel battery vehicle and includes an existing steel-made tank, a fiber-reinforced composite material for the underground which is provided in the inner periphery of the steel-made tank and prevents oil leakage from the steel-made tank and a solvent-resistant film which is provided in the inner periphery of the fiber-reinforced composite material for the underground and comes in contact with the solvent to be stored.SELECTED DRAWING: Figure 1 |
