Quick Reference Guide
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)
