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?0 ]' o9 E& r. _9 c: i

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。

Approximate maximum pressure, aluminum 175 bars (17.5 MPa; 2,540 psi), steel 200 bars (20 MPa; 2,900 psi). |
