Abstract
In order to limit entry of a fuel cell stack into a passenger compartment by a simple structure, the fuel cell stack is accommodated in an accommodating compartment formed at a rear of a passenger compartment. A force receiving member is arranged forward with respect to the fuel cell stack and below the fuel cell stack so that rearward force acts on the force receiving member at the time of vehicle collision. When the rearward force acting on the force receiving member due to vehicle collision is larger than a predetermined upper limit value, the rearward force is converted into upward force, and the upward force is transmitted to a forward bottom surface of the fuel cell stack, whereby a forward end part of the fuel cell stack is lifted up with respect to a rearward end part of the fuel cell stack upon vehicle collision.
Claims11
An electric vehicle accommodating a fuel cell stack in an accommodating compartment formed at an outside of a passenger compartment in a vehicle length direction, wherein the fuel cell stack has a generally rectangular shape and is flat in configuration with a height smaller than a length and width, wherein the fuel cell stack is arranged in the accommodating compartment so that the two largest surfaces among surfaces of the fuel cell stack form a top surface and bottom surface of the fuel cell stack, wherein a force receiving member is arranged at the outside in the vehicle length direction with respect to the fuel cell stack and below the fuel cell stack so that force toward the inside in the vehicle length direction acts on the force receiving member at the time of vehicle collision, and wherein the electric vehicle is further provided with a force transmission mechanism which, when force acting on the force receiving member directing inward in the vehicle length direction due to vehicle collision is larger than a predetermined upper limit value, converts the inward force to upward force and transmits the upward force to the bottom surface of the fuel cell stack at the outside in the vehicle length direction, whereby, at the time of vehicle collision, an end part of the fuel cell stack at the outside in the vehicle length direction is lifted up with respect to an end part of the fuel cell stack at the inside in the vehicle length direction.
