The present invention discloses a fuel cell electric vehicle. The fuel cell electric vehicle comprises a fuel cell, the fuel cell comprises a plurality of single cells arranged side by side, each single cell comprises a cathode plate and an anode plate which are oppositely arranged, and cooling liquid conveying openings and anode gas conveying openings which are through in the thickness directionare correspondingly formed in the cathode plate and the anode plate; and the number of the cooling liquid conveying openings and the number of the anode gas conveying openings are both two. The middlepart of one side of the cathode plate is provided with an air flow channel arranged in a transverse or longitudinal penetrating manner, and the other side of the cathode plate is provided with a first cooling liquid flow channel communicated with the two cooling liquid conveying openings; an anode flow field area is arranged in the middle of one side of the anode plate, anode flow channels are formed in the anode flow field area at intervals, and the anode flow channels are communicated with the two anode gas conveying openings; and the other side of the anode plate is provided with a secondcooling liquid flow channel communicating with the two cooling liquid conveying openings. The power generation device has the advantages of reasonable structural design, good heat dissipation effect,capability of improving the power generation efficiency and the power density, contribution to improvement of the cruising ability and the like.
