According to the present invention, provided is a thermo-sensitive pressure safety apparatus for a fuel cell vehicle. The apparatus includes: a hollow body part mounted beside an outlet of a hydrogen tank; a hydrogen discharge block provided in a structure, in which a plurality of first hydrogen discharge holes are formed, to be fixed to an upper part in the hollow body part; a hydrogen discharge pipe provided in a structure, in which a plurality of second hydrogen discharge holes are formed, to be connected to the bottom of the hydrogen discharge block; a piston inserted into an outer diameter part of the hydrogen discharge pipe to be elevatable to open or close the second hydrogen discharge holes; a stopper formed in a lower part in the hollow body part to limit a falling distance of the piston; and a melting alloy placed between the piston and the stopper to be melted at no less than a predetermined temperature. Therefore, the present invention is capable of improving durability and preventing malfunction.
