Abstract: A system control method is provided for measuring a distance between a smart key and a vehicle. When the distance between the smart key and the vehicle is changed based on a predetermined distance whether a hydrogen leak occurs is detected by a hydrogen sensor detection controller. A driver is then informed of a hydrogen leak via a display on a cluster, a turn-on of an emergency light, and a warning sound of the vehicle. Alternatively, a starting-impossible state of the vehicle or shutting-down starting of the vehicle is maintained to ensure safety measures based on the concentration of the leaking hydrogen.

Abstract: An apparatus is provided for safely discharging hydrogen permeated and leaking from a fuel tank of a fuel cell vehicle. The hydrogen exhaust apparatus for a fuel cell vehicle collects and safely processes hydrogen permeating a tank, and quantitatively detects the hydrogen transmissive amount. Thus the apparatus has improved a shape and attachment manner of a dome protector mounted in a hydrogen fuel tank. The safety aspect of hydrogen discharged to the air is improved, and an active response to various controls by quantitatively detecting the hydrogen transmissive amount is implemented.

Abstract: A method is provided for notifying a driver that charging is required determined by utilizing the calculated remaining travel distance of the vehicle, the position information of the charging station and the position information about the destination. In particular, the method determines when the total travel distance in consideration of the destination exceeds the remaining travel distance of the vehicle. The driver is notified of the necessity for charging during the initial traveling, and before traveling beyond the rechargeable returning distance.

Abstract: Disclosed is a method and related system of regenerating a raw material for a hydrogen supply system of a fuel cell. The method includes reacting aluminum and a metal hydroxide to produce hydrogen in the hydrogen supply system of a fuel cell; and recovering an aluminum compound produced simultaneously with the hydrogen in the reaction. An aluminum hydroxide is obtained from the aluminum compound. The aluminum hydroxide is heat-treated to obtain an aluminum oxide. The aluminum oxide is reduced to obtain aluminum. The obtained aluminum is re-supplied as a raw material for producing the hydrogen.
