Abstract: PURPOSE: A vehicle fuel cell apparatus and a control method thereof are provided to precisely estimate an amount of re-circulated hydrogen in order to always re-circulate a predetermined or greater amount of hydrogen. CONSTITUTION: A stack(30) is formed into an aggregate of unit cells which generate electrical energy using an electrochemical reaction between fuel and oxidizer. A blower(50) re-supplies a re-circulated gas to the stack by re-circulating a gas discharged from the stack. An ejector(60) supplies a mixing gas of the re-circulated gas and hydrogen to the stack by re-circulating the gas discharged from the stack. A sensor part measures an operation state of a vehicle. A controller controls the operation of the ejector and the blower using a performance map of the ejector and the blower and the operation state of the vehicle. The performance map of the blower stores an amount of re-circulated hydrogen according to a blow rotation number and a pressure difference between an exit and an entrance of the stack.
