Characteristics of Fuel Cell Vehicles
A fuel cell vehicle (FCV) converts hydrogen gas into electricity which is used to power an electric motor. The FC (fuel cell) system comprises
of hydrogen tanks and an FC stack, as well as other components, and requires a constant supply of hydrogen fuel, and proper cooling and
ventilation to generate electricity.
The FC stack is the main power unit which comprises of a series of fuel cells joined together or “stacked” on one another. With in each fuel
cell, a process that combines hydrogen and oxygen results in an electric current which is used to not only power the motor but also charge a
High Voltage battery. This High Voltage battery provides supple mentary power to assist the FC power system when the vehicle is subjected
to heavy acceleration.
Unlike vehicles that use internal combustion engines, FC vehicles emit no harmful emissions such as CO
2 and NOx, and are thus considered
environmentally responsible. The only substance discharged from the tailpipe is water, in the form of both liquid and vapor.
FC Stack
Fuel cell power output may decline faster than usual under the following circumstances:●The vehicle is frequently used in sub-zero temperatures over extended periods of time.●The vehicle is repeatedly left in standby state for extended periods of time.●The FC system is subjected to frequent starting and stopping.●Salt water has permeated the air cleaner element.
u Replace the air cleaner element and clean the surrounding area. For details, consult an authorized Honda Clarity Fuel Cell deal er.
●The vehicle is driven extensively in areas whose air contains high levels of:
Dust
Sulfur (common to hot spring and volcanoes)
Organic solvents, e.g., paints and thinners
Amine-related substances, e.g., ammonia
Chlorinated substances, e.g., salt and snow-melting agents
u Once the vehicle is driven in a normal environment again, fuel cell power output will return over time.
In the following circumstances, power output may be temporarily limited:
●You are repeatedly accelerating and decelerating aggressively.●You are ascending a slope or driving at high altitudes above 6,562 feet (2,000 meters). 2 Driver Information Interface Wa rning and Information Messages (P106)

Quick Reference Guide
Fuel Cell Power System
The fuel cell power system regulates the fuel cells to maintain efficient power generation in various driving conditions. The p ower system is
unique to fuel cell vehicles and differs from those used in conventional internal combustion vehicles or electric vehicles in t he following
ways:
●Depending on circumstances, the system may n eed to adjust the condition of the fuel cells before shutting down; therefore, the power
system may continue to operate even after the power mode is set to OFF.
●In cold temperatures, the power system may take more time to sta rt or stop than usual as the fuel cells need to be conditioned before
they can generate power.
Hydrogen Tanks
●Outline
The hydrogen tanks are the storage containe rs that house the compressed hydrogen gas.
●Inspection
Owners of fuel cell vehicles are required by law to have these tanks inspected periodically. Filling a hydrogen tank with compr essed
hydrogen gas is prohibited by law if the tank has not passed inspection or if the tank has expired.
The hydrogen tanks are affixed with an expiration date. This da te is also affixed to the underside of the hood and the hydrogen fuel lid. If a
tank has expired, replace it immediately.
●Disposal
Disposal of hydrogen tanks or hydrogen tank valves must be done in accordance with the pertinent rules and regulations of the state or
region within which the tanks or valves are to be disposed of. For details, consult an authorized Honda Clarity Fuel Cell deale r.
●Theft
If your fuel cell vehicle is stolen, be sure to inform the polic e that the vehicle is equipped with tanks filled with compresse d hydrogen gas.
Refueling
Fuel cell vehicles need hydrogen to run. Refuel with compressed hydrogen gas at an authorized hydrogen filling station.

Quick Reference Guide
Sounds Unique to the Fuel Cell Vehicle
When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particularly when you first turn on the power system,
while driving, and just after parking. Some of these sounds are unique to this ve hicle’s powertrain, fuel, and climate control systems; others
are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a vehicle of this design.
These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any new or unus ual noise
should one develop.
Certain sounds associated with your vehicle may be caused by:
●Pressurized intake air being released through the rear of the vehicle.
u This can happen if the accelerator is released suddenly when the vehicle is under a heavy load, such as when climbing a hill.
●The power system warming up.
u This sound is particularly loud when temperat ures are extremely low (below –4°F [–20°C]).
●Hydrogen gas flowing through the fuel line during refueling.

a Hydrogen Ventilation Duct
Fuel cells consume oxygen when generating
electricity. If the vehicle is left in standby
state in an enclosed area, the air may
become deprived of oxygen, resulting in
asphyxiation of any person(s) in the area.
Make sure the area is well ventilated before
turning the power system on. If the vehicle
is in a garage, keep the door open.
WARNING
Never leave the fuel cell vehicle in standby
state in an enclosed area that has limited
ventilation as there is a risk of oxygen
deprivation.
WARNING
Do not attempt to modify, install, or
disassemble the hydrogen-related
components.
The hydrogen-related components are
filled with hydrogen gas. Removing or
disassembling these components may cause
a hydrogen gas leak which can lead to a fire
or explosion.
If you notice anything unusual about your
vehicle, consult an authorized Honda
Clarity Fuel Cell dealer.
