另外,toyota 用的储氢罐在wiki上是这么写的:

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 HydroGen4.9 z: j% _8 P& Q9 U

从储氢罐到 fuel cell 的管道也可能都用得是这种材料。- t# ?7 C! b' j% Y, o6 w
