Abstract: PURPOSE: A catalyst electrode for a fuel cell is provided to improve catalyst activation and oxidation-reduction property due to high interaction with a catalyst through a fuel cell test by using titanium nitride as a supporter and to secure stability even in case of being operated in a long time. CONSTITUTION: A catalyst electrode for a fuel cell uses titanium nitride nitrided in titanium oxide through a thermal process as a supporter of a catalyst. A method for manufacturing the catalyst electrode for a fuel cell comprises the steps of: evenly spreading titanium oxide on a boat, putting the boat in an electric furnace, and flowing nitrogen gas to make a nitrogen atmosphere; flowing ammonia gas while raising the nitrogen atmosphere temperature to a preset temperature for a predetermined time; and nitriding the titanium oxide by maintaining the preset temperature for a predetermined time.

Abstract: An apparatus for restricting a door outside handle is provided to prevent a door from being unintentionally opened by preventing a handle lever from being rotated upon a side collision. An apparatus for restricting a door outside handle comprises a locking groove(21b), a guide bracket(30), a locking bracket(40), a central shaft member(50) having two ends fixed to the hand lever, and a locking bracket operating member(60), which connects the locking bracket to the central shaft member and is operated by inertial force. The locking groove is formed at one side(21a) of a handle housing(21), which faces the handle lever(22). The guide bracket is mounted on an inner side of a handle lever(22) and has a guide groove(31) extending lengthwise along the handle lever. The guide bracket has a first end corresponding to the locking groove and a second end disposed in a longitudinal direction. The locking bracket has a guide projection(41) inserted into the guide groove and has a front end selectively inserted into the locking groove.
