Hydrogen fuel filling system and hydrogen fuel filling method

A hydrogen fuel filling system according to an embodiment of the present invention is characterized by being provided with: a first flow channel through passes which hydrogen fuel supplied from a pressure accumulator in which the hydrogen fuel is accumulated; a second flow channel which is disposed in parallel with the first flow channel and through which the hydrogen fuel supplied from the pressure accumulator passes; a switching valve for selectively switching the flow channel from one of the first and second flow channels to the other thereof, or switching the flow channel between one and both of the first and second flow channels; and a control circuit for controlling the opening and closing of the switching valve; a fuel cell automobile using hydrogen fuel as a power source being filled with the hydrogen fuel while the flow channels are switched by the switching valve during supplying from the pressure accumulator. 本发明的一个方式的氢燃料的填充系统的特征在于，具备：第一流路，其供从对氢燃料进行了蓄压的蓄压器供给来的氢燃料通过；第二流路，其与第一流路并列地配置，供从蓄压器供给来的氢燃料通过；切
