另外,toyota 用的储氢罐在wiki上是这么写的:* a* N& q6 V1 A2 `
% P( B9 M& |! r# h* O7 lA 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.% f1 p# a1 p/ Z1 }, y

那么, type IV hydrogen tank 是个什么东西呢?

Composite tanks such as carbon fiber with a polymer liner (thermoplastic). See rotational molding and fibre-reinforced plastic.

从储氢罐到 fuel cell 的管道也可能都用得是这种材料。
