  • Page 6: Vehicle Description

    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.

    Vehicle Description One of Two Assemblies in the Capacitor Module High-Voltage Cables (driver’s-side under-hood view) 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.

  • 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.

  • Page 11: Potential Hazards

    1 to 7.6% 1.1 to 3.3% Gasoline Hydrogen 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.

    Emergency Procedures 12V Battery Battery Negative Ground Bolt Ground Bolt 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.
