, J: o% Q. U: 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.
