Fuel cell hose with barrier properties |
摘要 |
The present invention is directed to a flexible hose for transporting hydrogen and oxygen gases for use in a fuel cell vehicle. The hose has a low permeation rate and will not contaminate the fuel cell system due to interactions between the hose and the transported gases. The hose has a multi-layer inner tube, a reinforcing layer, and a cover layer wherein the multi-layer inner tube is characterized by the innermost layer being formed from a liquid crystal polymer. A second low permeability layer may be present radially outward of the liquid crystal polymer.
