Hydraulic system
A hydraulic system that can implement effective practical use of energy is provided. A hydraulic system according to the present invention has a hydraulic pump driven by a hydraulic pump motor, a loading cylinder and a power steering cylinder which are driven by pressure oil supplied from the hydraulic pump, and power supply means for supplying power to the hydraulic pump motor. The power supply means comprises a stack of a fuel cell, a fuel supply passage for supplying hydrogen gas to the stack, fuel circulating passages in which a hydrogen pump for joining unreacted hydrogen gas discharged from the stack into the fuel supply passage to circulate hydrogen gas is disposed, and a regenerator which is driven by pressure oil to generate rotational force. The hydrogen pump is rotationally driven by the regenerator.
