Saddle riding type fuel cell vehicle

Abstract

The invention provides a saddle riding type fuel cell vehicle capable of: reducing pressure loss by shortening a cooling water pipe; and improving the cooling effect of a fuel cell. The saddle riding type fuel cell vehicle includes: a fuel cell that generates power by a chemical reaction between a fuel gas and a reactive gas; radiators that cool cooling water of the fuel cell; and a seat on which a driver sits. In the saddle riding type fuel cell vehicle, the radiators are adjacently arranged in right and left sides of the fuel cell in a vehicle width direction. The radiators, each outer end surface outside in a vehicle width direction is positioned closer to the front side of a vehicle body than each inner end surface inside in the vehicle width direction; Thus, each plane portion, which receives traveling wind, is inclined to the inner side of the vehicle body, and air courses, which allow traveling wind to be passed to the rear side of the vehicle body, are each formed between the inner end surface of each of the radiators and each side surface of the fuel cell. Moreover, a rear end portion of the lower surface of each of the radiators is placed more backwardly than the fuel cell in a vehicle body side view.

Description

technical field [0001] The invention relates to a straddle type fuel cell vehicle, in particular to a straddle type fuel cell vehicle which not only shortens the cooling water pipeline to reduce the pressure loss, but also improves the cooling effect of the fuel cell. Background technique [0002] From the point of view of the prior art, in the known fuel cell vehicles, a fuel cell is usually mounted, and the electric power supplied by the fuel cell is used for running. The chemical reaction of the oxygen in the battery produces electricity. When the fuel cell is working, the reaction heat of the chemical reaction will cause its internal temperature to rise. At this time, in order to carry out the chemical reaction more effectively, the temperature of the fuel cell needs to be kept within a certain range. Therefore, a cooling system needs to be configured on the fuel cell vehicle to cool the fuel cell. [0003] Japanese Invention Patent Laid-Open Publication No. 2006-56427...

Problems solved by technology

[0004] However, since the structure of this patent document increases the distance between the radiator and the fuel cell disposed approximately in the middle of the vehicle body in the front-to-rear direction, this structure makes the cooling water line longer.

In this way, not only the pipeline structure becomes complicated, but also the pressure loss of the pipeline is increased. Therefore, it is necessary to use a large water pump for pumping cooling water.
