Toyota FCHV

The FCHV in Fig. 4-3 stores hydrogen in four 35 megapascal (MPa), equal to 5000 pounds per square inch (psi), high-pressure tanks. The system combines hydrogen from the tanks with oxygen from the air to generate 90 kW of electric power. The maximum speed of the Toyota FCHV is 155 kilometers per bour, and the range is 300 kilometers (km) measured by the Japanese 10-15 test mode, or somewhat less if tested on standard U.S. test cycles.

Toyota s prototype, the FCHV, is based on the Toyota Highlander and has been refined several times since being introduced in 2001. The electricity produced in the fuel cell is used to power the electric engine and charge the battery. The Toyota FCHV, a refinement on their FCHV-4 model, was introduced to the market in 2002 with two FCHVs leased in California and another two leased in Japan, where the vehicle underwent 18 months of real-world testing (Toyota 2005a). The FCHV has four 5000 psi fuel tanks and a cruising distance of over 150 miles.
