Abstract
A hydrogen fuel hose having a wall composed of an inner resin layer, a thin metal layer and an outer resin layer. The inner resin layer includes at least a layer of low gas permeability and may further include a layer of low water permeability surrounded by the layer of low gas permeability. The hose may have a corrugated wall portion. The hose is suited for use as a hydrogen fuel hose for a fuel-cell vehicle because of its excellent hydrogen gas impermeability, resistance to embrittlement by hydrogen and hose flexibility.
