Abstract
Disclosed is a high pressure tank configured to store hydrogen and includes a metal hydride (MH) tank capable of storing hydrogen, mounted therein. First and second solenoid valves are provided at both ends of the high pressure tank. A fuel cell stack is then connected to the buffer tank so that hydrogen from the high pressure tank or the MH tank is supplied to the stack through the buffer tank.
