General Motors said it completed the first successful vehicle test
of a 10,000 PSI hydrogen storage system, allowing the company to
increase the driving range of its compressed hydrogen fuel cell
vehicles. General Motors developed the system with Quantum Fuel Systems
Technologies Worldwide Inc., Irvine, Calif.
General Motors said it achieved the 10,000 PSI milestone, which
extends the range of its HydroGen3 fuel cell vehicle by 60 percent to 70
percent compared to an equivalent-sized 5,000 PSI system, more than a
year before the stated goal of other auto companies.
The TriShield tank design General Motors and Quantum Fuel use
features a one- piece permeation-resistant seamless liner, a
high-performance carbon composite over-wrap for strength and an
impact-resistant outer shell.
