The new FCX offers superior safety measures for handling hydrogen and high-voltage electricity.

The FCX layout positions the fuel cell system box under the floor and the high-pressure hydrogen tanks under the rear seat, completely isolating the cabin from all hydrogen and high-voltage lines. Hydrogen sensors are located throughout the vehicle to provide a warning in the unlikely event of a hydrogen leak. Should a hydrogen leak occur inside the fuel cell system box, a forced ventilation system is activated and an automatic cut-off system closes the main stop valves on the hydrogen tanks or appropriately located cut-off valves on the supply lines as necessary. The high-voltage lines are electronically full-floating. If grounding occurs, a sensor sends a warning, and in the event of a collision a contact mechanism shuts down the source power line. Repeated floodwater testing and fire tests have confirmed a high level of safety and reliability.

Instrument panel warning display
Hydrogen leak warning system
When hydrogen sensors detect hydrogen leakage over a predetermined amount, a warning lamp lights up on the instrument panel. If necessary, the fuel line is automatically shut off.
