    Hydrogen Decal (1,680 kg). Fuel Cell Module The main power source for the FCX is a fuel cell module, which is housed inside a strong steel box under the passenger compartment floor. This module contains many individual fuel cells that combine hydrogen from onboard tanks with oxygen from the air intake units to produce electricity.
  • Page 7: High-Voltage Electric Motors

    Vehicle Description Continued High-Voltage Electric Motors Electricity generated by the fuel cell module powers these four high-voltage motors: • The propulsion motor drives the front wheels • An air compressor motor supplies air to the fuel cells • A water pump motor cools the fuel cell module •...
  • Page 8: Capacitor Module

    Vehicle Description Continued Capacitor Module Two integrated capacitor assemblies make up the capacitor module. Somewhat like a battery, the capacitor module provides long- term storage for electrical power generated by the fuel cells or regenerated by the propulsion motor. This power is available to provide extra current when needed, such as during acceleration.

    Built-In Safety Features Occupant Protection Features The FCX has lap/shoulder belts in all four seating positions, dual front airbags, and pyrotechnic seat belt tensioners for the driver and a front passenger. To disable the airbags and tensioners, the key switch must...
  • Page 10: Hydrogen Line Sensors

    Manual Hydrogen Shut-Off Valve The FCX is equipped with a manual shut-off valve that can be used to stop the flow of hydrogen from the tanks. The valve is located inside the right rear wheelwell, in front of the tire.

    The FCX does not present any greater hazards than a conventional gasoline-powered passenger car or any other type of electric car. It performed well in front-, offset-frontal-, side-, and rear-impact tests, with no damage to any of the high-voltage or hydrogen components.
  • Page 12: Electric Shock Potential

    Potential Hazards Continued Electric Shock Potential Unprotected contact with any electrically charged or “hot” high-voltage component can cause serious injury or death. However, receiving an electric shock is highly unlikely due to these facts: • Contact with high-voltage components inside the power control unit, the fuel cell box, or the capacitor module can occur only if these units are damaged and someone deliberately touches...

    Incidents Involving Fire If an FCX is involved in a fire, follow standard fire-fighting procedures, but keep away from the rear of the vehicle until the fire is completely out. Remember that high...
  • Page 14: Damaged Vehicle

    Emergency Procedures Continued Damaged Vehicle Before attempting to rescue occupants from a damaged FCX or to move a damaged vehicle, it’s important to prevent electric current from flowing through the high voltage cables and to prevent hydrogen leakage. You have three ways to do this, ranging from the best method to the least desirable.
  • Page 15: Best Method For Preventing Current Flow And Hydrogen Leakage

    Emergency Procedures Continued Best Method for Preventing Current Flow and Hydrogen Leakage Turn the key switch off, remove the key, and turn off the manual hydrogen shut-off valve. Turning off the key switch turns off the fuel cell module and all the motors, preventing electric current from flowing into the high-voltage cables.
  • Page 16: Second-Best Method For Preventing Current Flow And Hydrogen Leakage

    Emergency Procedures Continued Second-Best Method for Preventing Current Flow and Hydrogen Leakage Disconnect the 12-volt battery negative cable and the negative DC-to-DC converter cable, then turn off the manual hydrogen shut-off valve. This method should be used only if the key switch is in the ON (II) position, and you cannot reach the key but you can reach under the hood.
  • Page 17 Emergency Procedures Continued 4. Locate the red handle of the manual hydrogen shut-off valve (it’s in front of the tire in the right rear fenderwell). 5. Turn the handle one-quarter turn clockwise to stop the flow of hydrogen. Manual Hydrogen Shut-Off Valve (Turn 1/4 turn clockwise to stop the flow of hydrogen.)
  • Page 18: Least-Desirable Method For Preventing Current Flow And Hydrogen Leakage

    Emergency Procedures Continued Least-Desirable Method for Preventing Current Flow and Hydrogen Leakage Turn off the capacitor module main switch, then turn off the manual hydrogen shut-off valve. This method does not disable the airbags or the seat belt tensioners. It should be used only if the key switch is in the ON (II) position, you cannot reach the key, and you cannot reach under the hood.
  • Page 19 Emergency Procedures Continued 3. Remove the red locking cover, then flip the switch from ON to OFF. 4. Reattach the locking cover to prevent the switch from inadvertently being flipped on. Red Locking Cover 5. Locate the red handle of the manual hydrogen shut-off valve (it’s in front of the tire in the right rear fenderwell).
  • Page 20: Extricating Occupants

    Emergency Procedures Continued Extricating Occupants If you need to break windows, cut into the body, or use “Jaws of Life”-type equipment to remove occupants from a damaged vehicle, be sure to stay within the cut zone (as indicated on the illustration by the light blue and dark blue diagonal lines).
  • Page 21: Emergency Towing

    Emergency Towing Continued If you need to move the FCX only a short distance, such as to the side of the road, and the car can still roll on the ground, the easiest way is to shift to neutral, then push the car manually.
  • Page 22: Using The Tie-Downs

    Emergency Towing Continued 2. Remove the round grommet that covers the towing hook hole (on the driver’s side of the front grille). 3. Screw the towing hook firmly into the hole. Towing Hook Hole Using the Tie-Downs Tie-down points are provided on the inside of the side sills.
