To provide a fuel cell vehicle capable of further shortening a standby time at the start-up time while obtaining power generation stability of a fuel cell system, and a method for starting the fuel cell vehicle.SOLUTION: A fuel cell vehicle 11 is equipped with a fuel cell system 10 including a fuel cell stack 12 and a battery Bt. Further, the fuel cell vehicle 11 controls the operation of the fuel cell system 10 by ECU 82 to perform standby power generation from start-up until running is permitted and also perform power generation under driving after the running is permitted. In a start-up method, a power generation current is increased so as to follow a low-temperature efficiency rate Rl during power generation under driving, generated power is charged to a battery Bt under standby power generation, and the power generation current is increased so as to follow a standby stabilization rate Rw having a lower increasing rate than the low-temperature efficiency rate Rl.SELECTED DRAWING: Figure 5
【課題】燃料電池システムの発電安定性を得つつ、起動時の待機時間を一層短くすることができる燃料電池車両、及び燃料電池車両の起動方法を提供する。【解決手段】燃料電池車両11は、燃料電池スタック12と、バッテリBtとを有する燃料電池システム10を搭載している。また燃料電池車両11は、ECU82により燃料電池システム10の動作を制御して、起動から走行を許可するまで待機発電を行うと共に、走行を許可した後に運転中発電を行う。起動方法では、運転中発電において低温時効率化レートRlに沿うように発電電流を上昇させ、待機発電において発電電力をバッテリBtに充電すると共に、低温時効率化レートRlよりも上昇率が低い待機時安定化レートRwに沿うように発電電流を上昇させる。【選択図】図5
