A hydrogen fuel transporting hose for a fuel cell powered vehicle having a
laminar structure includes at least one inner rubber layer, at least one
reinforcing layer, and at least one outer rubber layer, which layers are
laminated integrally with one another in the order of description in a
radially outward direction of the hose. Each of the inner and outer rubber
layers are obtained by vulcanizing a rubber composition including a rubber
material selected from the group consisting of a halogenated butyl rubber
material, and a blend of a halogenated butyl rubber material and a butyl
rubber material. The vulcanized rubber includes a filler having a layered
crystal structure and is vulcanized with one of a peroxide vulcanizing
agent and a resin vulcanizing agent.
