另外,toyota 用的储氢罐在wiki上是这么写的:! y5 ~6 }; m* x2 q1 l
0 W0 U x( R9 \" p& C/ q8 fA 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.

看介绍,目前趋势是低压储氢系统,比如30bar, 440psi的系统。这样可以用type I 的罐子。从减轻死重的角度,会用铝罐。$ Z/ E$ B2 s" g( n/ u5 P
