Abstract: A system for controlling low-temperature starting of a fuel cell vehicle includes a high-pressure hydrogen flow control valve controlling a flow of hydrogen supplied to a fuel cell stack. A fuel cell controller is configured to change and control an opening rate of the high-pressure hydrogen flow control valve when an internal temperature of the fuel cell stack is a reference value or less. When the opening rate of the high-pressure hydrogen flow control valve decreases, a pressure of the hydrogen passing through the high-pressure hydrogen flow control valve decreases to increase a temperature of the hydrogen which is supplied to the fuel stack.

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.
