Abstract
In a fuel evaporator provided with an evaporation chamber that produces raw fuel gas FG by vaporizing raw fuel liquid by heat received from a plurality of heat medium tubes through which a high temperature heat medium passes, a raw fuel injection portion that injects raw fuel liquid onto the heat medium tubes is situated in the evaporation chamber . The heat medium tubes are arranged sparsely near the raw fuel injection portion and densely away from it. A catalytic combustor is provided adjacent to the bottom surface of the evaporation chamber to form the high temperature heat medium. Such a fuel evaporator efficiently vaporizes raw fuel liquid and can be suitably applied in a fuel cell system for a fuel cell-powered automobile.
