PROBLEM TO BE SOLVED: To provide a fuel evaporator which effectively evaporates an original liquid fuel, and can be appropriately adaped to a fuel cell system in a fuel cell electric car. SOLUTION: In a fuel evaporator 1 including an evaporation chamber 11 for generating original fuel gas FG by evaporating an original liquid fuel using heat obtained from pluralities of heat media tubes 12 through which high- temperature heat media is passed, an original fuel injection part for injecting the original liquid fuel into the heat media tubes 12 is installed in the evaporation chamber 11. The heat media tubes 12 are arranged sparsely near the original fuel injection part but densely away from the original fuel injection part. |
