To provide a fuel taking-out/vaporization accelerating unit capable of sufficiently utilizing a function of oxidation catalyst by accelerating the vaporization of fuel, while removing the dangerousness and botheration in pouring the fuel and the botheration in packing and unpacking.

The fuel is absorbed and solidified in a gelling or absorbing material (pipe and the like), and put in a metallic case (aluminum, stainless and the like) safe and easily in its handling, and an upper lid part is sealed by metallic foil (aluminum, stainless and the like). The metallic foil lid part is broken by a tip part of the vaporization accelerating unit, and the vaporization is accelerated by utilizing an absorbing member such as ceramic, glass fiber and the like on a tip end part of the vaporization accelerating unit, when being used. A metallic part of an outer periphery of the vaporization accelerating unit transfers the heat generation temperature of the oxidation catalyst body to accelerate the vaporization by the heat from the inside of a fuel container.
