另外,toyota 用的储氢罐在wiki上是这么写的:
$ k8 G t0 Y3 T: H) r6 n0 a h6 E, e6 w( e g% ~8 o" K
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.

那么, type IV hydrogen tank 是个什么东西呢?2 D) V' C; ^) C6 T& u, a. t& N

从储氢罐到 fuel cell 的管道也可能都用得是这种材料。
