Fuel cell vehicle having support frame which couples side frames in width direction of vehicle

Abstract

A fuel cell vehicle includes: a motor chamber provided in a front part of the vehicle; side frames extending on right and left sides of the vehicle in a front-to-back direction of the vehicle; a fuel cell; a motor for driving the vehicle, wherein the motor is driven using electric power generated by the fuel cell, and the fuel cell, the motor, and the side frames are installed in the motor chamber; and a support frame for coupling rear portions of the side frames with each other in a width direction of the vehicle, and for supporting the fuel cell installed on the support frame, wherein the motor is arranged below the support frame. The fuel cell vehicle may further include a guide member for guiding the motor toward a lower-back side of the support frame when a front collision of the vehicle occurs.
