NOVELTY - A fuel cell electric vehicle comprises a driving motor (40) between a pair of wheels; a fuel cell (10) having unit cells stacked in a vertical direction of a vehicle, and including through-manifolds to distribute a fuel gas, an oxidizing gas and a coolant to the unit cells; and first and second supply/discharge manifolds (20) disposed adjacent to first and second lateral end portions of the driving motor, respectively, with respect to a lateral direction of the vehicle.    USE - Used as fuel cell electric vehicle.    ADVANTAGE - The electric vehicle can increase output power of the fuel cell by increasing the number of unit fuel cells stacked together to form a fuel cell stack. The height of the manifolds can be increased without interfering with the large-diameter portion of the driving motor, thus more water produced by chemical reaction can be accumulated inside the manifolds, the water produced by the fuel cell stacks (10A, 10B) can be discharged more easily, and the fuel cell is less likely to have inadequate power generating performance due to flooding. The sealing properties of the overall connection surfaces between the manifolds and the fuel cell stacks can be improved. Since the size of the manifolds can be minimized, the size and weight of the fuel cell system as a whole can be further reduced.    DETAILED DESCRIPTION - A fuel cell electric vehicle comprises a driving motor between a pair of wheels; a fuel cell having unit cells stacked in a vertical direction of a vehicle, and including through-manifolds to distribute a fuel gas, an oxidizing gas and a coolant to the unit cells; and first and second supply/discharge manifolds disposed adjacent to first and second lateral end portions of the driving motor, respectively, with respect to a lateral direction of the vehicle. The manifolds are fluidly coupled to the through-manifolds to transport the fuel gas, the oxidizing gas and the coolant relative to the fuel cell, and includes fluid connection ports for transporting the fuel gas, the oxidizing gas and the coolant at positions that overlap with positions of the through-manifolds formed in the fuel cell in a top plan view of the vehicle. One of the manifolds is configured to fluidly coupled to a fuel gas pipe (21) connected to a fuel gas storage device mounted on the vehicle. The manifolds are fixedly coupled to a pair of side frames (7) of a vehicle frame, respectively.
