另外,toyota 用的储氢罐在wiki上是这么写的:

' u1 Y1 \! h- u/ ]& H( H4 c* O) `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?

从储氢罐到 fuel cell 的管道也可能都用得是这种材料。
