: z$ B9 f' e* DA 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.

那么, type IV hydrogen tank 是个什么东西呢?, P( @# G# B+ [; J; f2 y

Composite tanks such as carbon fiber with a polymer liner (thermoplastic). See rotational molding and fibre-reinforced plastic. O5 ~2 H7 ? c1 @! I3 w

从储氢罐到 fuel cell 的管道也可能都用得是这种材料。
