PROBLEM TO BE SOLVED: To cool air supplied to a fuel cell using adiabatic expansion of a fuel gas without the need of an external power source, improve power generation efficiency of the fuel cell, and ensure the longer life of the fuel cell.SOLUTION: A fuel cell motorcycle 10 includes: a motor 15 that drives a driving wheel 14; an air-cooled fuel cell 20 that supplies electric power to this motor 15; and a fuel tank 21 that stores a fuel gas supplied to this fuel cell 20. The fuel cell motorcycle 10 includes an intake passage 74 supplying air for reaction and cooling to the fuel cell 20, arranges the fuel tank 21 that stores the fuel gas at high pressure on halfway along the intake passage 74, and cools the air passing through the intake passage 74 by means of adiabatic expansion of the fuel gas at a time of supplying the fuel gas from the fuel tank 21 to the fuel cell 20. |
