ALL

Check the iN VIN status for eligibility.

Failure to properly vent the hydrogen tanks and fuel lines prior to the fuel cell stack replacement can result in hydrogen
gas leaks.
Hydrogen gas is flammable and highly explosive. You can be seriously injured or killed if the leaking hydrogen gas is
ignited.
Turn off the fuel cell system, and keep heat, sparks, and flames away.
Always follow the precautions for the fuel cell system listed in the service information.
The power cables carry high voltage when the fuel cell system is energized. To avoid serious injury from electrical
shock, do not turn on the system with the power cables disconnected.

REVISION SUMMARY
•

This bulletin has been extensively revised, American Honda recommends reviewing the entire bulletin.

BACKGROUND
Water improperly discharged inside the fuel cell (FC) stack mixes with hydrogen and oxygen, generating hydrogen
peroxide. The hydrogen peroxide/water combination concentrates in one area, accelerating the deterioration of the
electrolyte membrane in the fuel cell. This deterioration can reduce fuel cell output.
There are three similar bulletins for the 2017-18 Clarity Fuel Cell:

CUSTOMER NOTIFICATION
Automobile Customer Service will notify lessees of affected vehicles and arrange an appointment with their dealer.
The fuel cell stack and stack kit are controlled parts and can only be ordered with an eligible VIN once this appointment
has been made. Before ordering a fuel cell stack and stack kit, do an iN VIN status inquiry to make sure the vehicle
needs a fuel cell stack replacement.
CORRECTIVE ACTION

donor.
There is a separate REPAIR PROCEDURE, WARRANTY CLAIM INFORMATION, and PARTS INFORMATION for
