Description

  The present invention relates to an intake structure for a fuel cell in a fuel cell vehicle, and a fuel cell-equipped motorcycle to which the structure is applied.

Conventionally, in an intake system of a fuel cell vehicle, there is one that supplies air (oxidant gas) supercharged by a supercharger to a fuel cell after humidifying by a humidifier. The exhaust from the fuel cell returns to the humidifier to extract moisture, and this moisture humidifies new intake air before the fuel cell is supplied. At this time, if the humidifier is too cold, the water vapor saturation is lowered and it becomes difficult to extract moisture. Therefore, the heating medium (cooling water) after cooling the fuel cell is circulated around the humidifier to heat the humidifier. (For example, refer to Patent Document 1).
