    摘要: A check valve is disposed in a hydrogen offgas circulation path which is connected to a fuel cell so as to flow the hydrogen offgas only in one direction. Inside a valve housing, a first compression chamber and a second compression chamber are provided such that a bulkhead is disposed therebetween. In the bulkhead 14, a first communication hole 18 and a second communication hole 19 are formed so as to communicate between the first compression chamber and the second compression chamber. In a first reed valve, an opening end is disposed upward and a fixed end is disposed downward. In a second reed valve, an opening end is disposed downward and a fixed end is disposed upward. By doing this, operability in the check valve after water has frozen can be improved.

    摘要: In a fuel evaporator provided with an evaporation chamber 11 that produces raw fuel gas FG by vaporizing raw fuel liquid by heat received from a plurality of heat medium tubes 12 through which a high temperature heat medium passes, a raw fuel injection portion that injects raw fuel liquid onto the heat medium tubes 12 is situated in the evaporation chamber 11. The heat medium tubes 12 are arranged sparsely near the raw fuel injection portion and densely away from it. A catalytic combustor 20 is provided adjacent to the bottom surface 11b of the evaporation chamber 11 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.
