<P>PROBLEM TO BE SOLVED: To provide an anode side hydrogen oxygen interface formation suppressing structure of a fuel cell electric vehicle capable of stably operating a stack even at start up or off of the fuel cell electric vehicle. <P>SOLUTION: The stack generating electric energy by electrochemical reaction of hydrogen and oxygen has a first hydrogen exhaust pipe changing flow of hydrogen gas exhausted from the stack at starting off by installing a three-way valve so as to exhaust supplied hydrogen to the anode side of the stack and exhausting nitrogen to the atmosphere in start up; and a second hydrogen exhaust pipe installed so as to nitrogenize the anode side by the reaction of air supplied through a check valve in starting off and hydrogen inside the first hydrogen exhaust pipe. <P>COPYRIGHT: (C)2008,JPO&INPIT |
