Honda’s FCX Clarity: How It Works
The key to a hydrogen-powered vehicle is the fuel cell stack (A), which operates like a miniature power plant, generating electricity to drive the car’s motor (B). By using compressed hydrogen stored in a tank (C) behind the rear seat and combining it with atmospheric oxygen, the process produces no CO2 or other pollutants. With thinner fuel cells and a smaller box than previous designs, the V Flow Honda FC Stack fits neatly into the car’s central tunnel between the front seats. When extra power is required for start-up and acceleration, electricity from the fuel cell stack is supplemented by a lithium-ion battery (D). When the car decelerates, the electric motor acts as a generator, converting kinetic energy into electricity, which is then stored in the battery.
