To provide a fuel cell vehicle which suppresses occurrence of a resonance phenomenon during travelling caused by a travel motor and a fuel cell stack.SOLUTION: A fuel cell vehicle 13 includes: a motor room 13f separated from a cabin by a barrier wall member 13W; a fuel cell stack 12 arranged in the motor room 13f through stack mounts 80a, 80b, 104; and a travel motor 100 arranged in the motor room 13f through motor mounts 101, 105, on a vehicle body 13a. Elastic coefficients of the stack mounts 80a, 80b, 104 of the fuel cell vehicle are set so that an anti-resonance frequency of rocking by the travel motor 100 caused by vibration of the vehicle body 13a during travelling, and a resonance frequency of rocking by the fuel cell stack 12 caused by the vibration of the vehicle body 13a during travelling coincide with each other.SELECTED DRAWING: Figure 1 【課題】走行用モータと燃料電池スタックとに起因する走行中の共振現象の発生を抑制する燃料電池車両を提供する。【解決手段】車体１３ａに、隔壁部材１３Ｗによって車室と隔離されるモータルーム１３ｆと、モータルーム１３ｆ内にスタックマウント８０ａ、８０ｂ、１０４を介して設置される燃料電池スタック１２と、モータルーム１３ｆ内にモータマウント１０１、１０５を介して設置される走行用モータ１００とを備えた燃料電池車両１３のスタックマウント８０ａ、８０ｂ、１０４の弾性係数を、走行中の車体１３ａの振動に起因する走行用モータ１００による揺動の反共振周波数と、走行中の車体１３ａの振動に起因する燃料電池スタック１２による揺動の共振周波数とが一致するように設定する。【選択図】図１
