High-pressure Hydrogen Tank
A 70 MPa high-pressure hydrogen tank developed by Toyota is installed in the
TOYOTA FCHV-adv. The latest 70 MPa tank features a polyamide resin liner in the
inner most layer of the tank due to its high strength and excellent hydrogen
permeation prevention performance. Increased tank capacity and reduced weight
have been achieved by using optimum materials, improving design and production
methods, and minimizing wall thickness by optimizing the winding angle, tension
and volume of the carbon fiber. This has contributed to significant improvement
in cruising range
