PROBLEM TO BE SOLVED: To provide a fuel carburetor capable of suppressing an increase in size of the fuel carburetor even when designing the fuel carburetor corresponding to low temperature starting period.SOLUTION: A fuel carburetor 13 for supplying a vaporized fuel to an energy output means for outputting energy by consuming the vaporized fuel comprises: fuel flow paths 14a, 15a through which the fuel flows; heat medium flow passages 14b, 15b through which a heat medium flows; and partition parts 13a, 13b for partitioning the fuel flow paths 14a, 15a and the heat medium flow passages 14b, 15b, wherein the fuel and the heat medium perform heat exchange while using the partition parts 13a, 13b as heat transfer inclusions to heat and vaporize the fuel. Furthermore, an inner fin 50 increasing a heat transfer area of the heat transfer inclusions in contact with the fluid and dividing the inside of the flow passage into a plurality of flow passages is disposed at at least one of the fuel flow paths 14a, 15a and the heat medium flow passages 14b, 15b. |
