Toyota Devises Hydrogen Tanks for Fuel Cell Cars

May 15, 2005 by Jeff Shepard

Toyota Motor Corp. (Nagoya, Japan) announced that it has developed two high-pressure hydrogen tanks that extend the cruising range of environmently friendly fuel cell vehicles. Capable of storing 35 MPa and 70 MPa of hydrogen, both tanks have been certified by the High Pressure Gas Safety Institute of Japan and are designed for use in Toyota's fuel cell hybrid vehicle (FCHV).

The 35 MPa tank holds 10% more hydrogen than a US-made tank of the same exterior size used by Toyota before, and extends the cruising range of the Toyota FCHV to 330 km from 300 km. The 70 MPa tank stores 1.7 times more hydrogen than the US-made 350 MPa tank, and realizes a cruising range of more than 500 km.
