Abstract

A high-pressure vessel having a gasket and a composite layer for reinforcing a periphery of the gasket, including: a cylindrical portion formed along an axial direction of the high-pressure vessel; and a top cover portion fastened to both ends of the cylindrical portion To close the high pressure container. The composite layer formed on the cylindrical portion is formed by alternately overlapping a plurality of hoop layers and a plurality of helical layers. A hoop layer disposed closer to the liner has a greater thickness than a hoop layer disposed further from the liner such that the thickness of the hoop layer decreases with increasing distance from the liner.

Description

technical field [0001] The present invention generally relates to a high-pressure vessel installed in a fuel cell system. More particularly, the present invention relates to a composite layer disposed on the periphery of a liner on a high pressure tank. Background technique [0002] Generally, a fuel cell system includes: a fuel cell stack that generates electric power; a fuel supply system that supplies fuel (hydrogen gas) to the fuel cell stack; an air supply system that supplies oxygen from the air to the fuel cell stack as required oxidant; thermal and water management systems, which control the operating temperature of the fuel cell stack, etc. [0003] The hydrogen tank included in the fuel supply system, that is, the hydrogen supply device, stores compressed hydrogen gas under a high pressure of about 700 bar, and thereafter, according to the opening / closing operation of the high pressure controller installed at the inlet portion of the hydrogen tank, The stored com...
