Abstract:
1. A hybrid-type power supplying apparatus comprising: a robot; a power management device that is connected to the robot; a fuel cell device that is connected to the power management device and includes a fuel cell stack and balance of plants for operating the fuel cell stack; a rechargeable battery that is connected to the power management device; and an operation control device that is connected to the fuel cell device and the power management device and controls the operation of the balance of plants, wherein the power management device manages the power from the rechargeable battery to be supplied to the fuel cell device as a driving power for the fuel cell device, and manages the power generated from the fuel cell stack to be supplied to the robot as a main power for the robot, when the total amount of power consumed in the robot, the balance of plants, the operation control device, and the power management device exceeds the power generated by the fuel cell stack, the power management device manages the loads of the rechargeable battery and the fuel cell stack so that power is supplied from the rechargeable battery to the robot as an auxiliary power for the robot supplementing the main power for the robot, wherein the balance of plants includes a fuel supply device and an air supply device, and the fuel supply device includes: a fuel storage device which stores fuel; a fuel mixer which is connected to the fuel storage device so as to supply fuel with a constant concentration to the fuel cell stack; a fuel recovery and supply device which recovers non-reacted fuel liquid from the fuel cell stack and then supplies the non-reacted fuel liquid to the fuel mixer; a water recovery and supply device which recovers water flowing with the air from the fuel cell stack and then supplies the water to the fuel mixer; and a concentration adjusting device which is connected to the fuel storage device and the water recovery and supply device and controls the fuel concentration of the fuel mixer at a constant concentration.
