PROBLEM TO BE SOLVED: To provide a fuel cell power generation system of a vehicle that is equipped with a fuel cell which is supplied with both modified fuel and pressure-fed air to generate power, which can enhance an energy efficiency of the fuel cell power generation system as a whole by utilizing braking energy of an axle at the time of vehicle decelerated travelling, a vehicle and a fuel cell power generation method of a vehicle.SOLUTION: At the time of vehicle decelerated travelling, a second air supply device 21 is activated by braking energy to be transmitted from an axle 30 so as to accumulate air in an air pressure accumulator 22. At the time of vehicle accelerated travelling or constant-speed travelling, when the air accumulated in the air pressure accumulator 22 is supplied to a fuel cell 10 through a second air supply passage 20 comprising an opening/closing valve 23, opening/closing control of the opening/closing valve 23 and activation control of the air supply device 11 are performed based on one or both of required generated-power to the fuel cell 10 and accumulated pressure V in the air pressure accumulator 22.SELECTED DRAWING: Figure 2
【課題】改質された燃料と圧送された空気の両方の供給を受けて発電する燃料電池とを備えた車両の燃料電池発電システムにおいて、車両の減速走行時の車軸の制動エネルギーを利用して、燃料電池発電システム全体としてのエネルギー効率を高めることができる車両の燃料電池発電システム、車両、及び車両の燃料電池発電方法を提供する。【解決手段】車両の減速走行時には、車軸30から伝達される制動エネルギーで第2の空気供給装置21を作動させて空気蓄圧装置22に空気を蓄圧し、車両の加速走行時または定速走行時には、空気蓄圧装置22に蓄圧された空気を開閉弁23を備えた第2の空気供給通路20を経由して燃料電池10に供給する際に、燃料電池10に対する要求発電力と空気蓄圧装置22の蓄圧量Vのいずれか一方又は両方に基づいて、開閉弁23の開閉制御と空気供給装置11の作動制御を行う。【選択図】図2
