另外,toyota 用的储氢罐在wiki上是这么写的:; g2 D: J4 u) U5 b! {; u
9 P% U( ]. t. d' W8 V! n! MA 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.
