A Hydrogen tank (other names- cartridge or canister) is used for hydrogen storage.[1][2][3] The first type IV hydrogen tanks for compressed hydrogen at 700 bars (70 MPa; 10,000 psi) were demonstrated in 2001, the first fuel cell vehicles on the road with type IV tanks are the Toyota FCHV, Mercedes-Benz F-Cell and the GM HydroGen4.+ m) f1 r( _+ h2 O* A2 P) E

Composite tanks such as carbon fiber with a polymer liner (thermoplastic). See rotational molding and fibre-reinforced plastic.- b! v( d' A& D4 {1 Q; e
Approximate maximum pressure, plastic/carbon 661 bars (66.1 MPa; 9,590 psi) and up.

从储氢罐到 fuel cell 的管道也可能都用得是这种材料。; G+ u: ^+ ], ]
$ f# k' G! h: w3 k看介绍,目前趋势是低压储氢系统,比如30bar, 440psi的系统。这样可以用type I 的罐子。从减轻死重的角度,会用铝罐。
