Claim of US Patent No. 10,368,470

1. A fuel cell vehicle comprising:a fuel cell;
a reactor unit including:
a plurality of reactors, and
a cooler configured such that a cooling medium flows in an inside of the cooler and the plurality of reactors are disposed on an outside of the cooler to cool the plurality of reactors, wherein
the plurality of reactors are disposed in at least one line on a reactor cooling surface that is one of outer surfaces of the cooler,
the cooler has a cooling medium flow passage that is in contact with an inner surface on a reverse side of the reactor cooling surface,
the cooling medium flows linearly from an inlet portion to an outlet portion of the cooling medium flow passage,
a direction in which the cooling medium flows inside the cooling medium flow passage is same as a direction in which the plurality of reactors are disposed in the at least one line,
cooling fins are provided on the inner surface on the reverse side of the reactor cooling surface, and
a longitudinal direction of each of the cooling fins is same as the direction in which the cooling medium flows inside the cooling medium flow passage; and
a fuel cell converter that converts output voltage of the fuel cell, wherein the fuel cell is disposed in a front compartment of the fuel cell vehicle, and the reactor unit included in the fuel cell converter is disposed above the fuel cell such that the plurality of reactors are disposed in a lower side and the cooler is disposed in an upper side.
