Abstract
Official abstract text for this publication.
An apparatus is provided for safely discharging hydrogen permeated and leaking from a fuel tank of a fuel cell vehicle. The hydrogen exhaust apparatus for a fuel cell vehicle collects and safely processes hydrogen permeating a tank, and quantitatively detects the hydrogen transmissive amount. Thus the apparatus has improved a shape and attachment manner of a dome protector mounted in a hydrogen fuel tank. The safety aspect of hydrogen discharged to the air is improved, and an active response to various controls by quantitatively detecting the hydrogen transmissive amount is implemented.
First claim
Opening claim text (preview).
What is claimed is: 1 . A hydrogen exhaust apparatus for a fuel cell vehicle, comprising: a dome protector attached to a dome portion of a fuel tank; a flow path formed inside the dome protector; and an outlet formed at one side of the flow path, wherein hydrogen permeating the fuel tank is collected inside the flow path and discharged through the outlet. 2 . The hydrogen exhaust apparatus of claim 1 , wherein the flow path formed in the dome protector includes: a plurality of concentric circular flow paths disposed in a concentric circle, and a plurality of radial flow paths radially disposed while in communication with the concentric circular flow paths. 3 . The hydrogen exhaust apparatus of claim 1 , wherein the outlet of the flow path formed in the dome protector is formed at a center portion of a dome. 4 . The hydrogen exhaust apparatus of claim 1 , wherein an exhaust pipe is connected to the outlet formed in the flow path of the dome protector, to mix hydrogen discharged through the outlet with air within the exhaust pipe and diluted, and to discharge to the air. 5 . The hydrogen exhaust apparatus of claim 1 , wherein the fuel tank includes a carbon composite material layer and a plastic liner layer. 6 . The hydrogen exhaust apparatus of claim 2 , wherein the outlet of the flow path formed in the dome protector is formed at a center portion of a dome.
