Problems solved by technology

[0006] However, in the above-mentioned prior art, the cooling mechanism for the pressure reducer has to be provided separately from the mechanism for cooling the fuel cell stack and the fuel tank.
Therefore, not only would the number of parts increase, the weight of the vehicle increase, and the cost would increase, but also a number of cooling mechanisms had to be arranged in the limited space of the motorcycle, so there were technical problems such as limiting the degree of freedom in design.

Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a partially cutaway side view showing the configuration of main parts of a fuel cell motorcycle of the present invention, and Fig. 2 is a perspective view thereof, image 3 It is a diagram schematically showing the frame structure.

[0035] The vehicle frame 10 includes: a head pipe 11, a pair of left and right upper brackets 13 (L, R) extending obliquely downward from the head pipe 11, and a pair of left and right upper brackets 13 (L, R) extending downward from the aforementioned upper bracket 13, starting from the aforementioned head pipe 11. A pair of left and right lower frames 12 (L, R) extending downward extend obliquely upward from the substantially central portion of the lower frame 12, and a pair of left and right top frames 14 ( L, R), and a left and right pair of underframes 15 (L, R) extending from the lower end of the lower brac...

Abstract

The vehicle has a combustible gas cylinder (41) containing a combustible gas. A cover covers the cylinder and forms a ventilation pipe extending from front of the vehicle up to a back of the vehicle. A down converter (84) is placed behind the cylinder so as to face a rear opening section of the ventilation pipe.

Description

technical field [0001] The invention relates to a fuel cell vehicle running with fuel cells as power energy, in particular to a fuel cell vehicle with a structure capable of effectively cooling electrical circuits. Background technique [0002] Conventionally, a fuel cell type motorcycle is known in which electric power generated by a fuel cell is supplied to an electric motor, and rear wheels are driven by the electric motor. In a fuel cell system, electricity is generated by the electrochemical reaction of hydrogen as a fuel gas and oxygen as a reaction gas, but this electrochemical reaction requires an appropriate reaction temperature, and the reaction rate decreases at low or high temperatures, especially when the temperature changes. When the value is too high, the life of the fuel cell will be shortened. Therefore, a cooling device is required in a fuel cell power generation system to discharge heat generated during fuel cell power generation to the outside of the fue...
