The Honda FCX Clarity, 1ere car fuel cell for consumers Source for figures and data: Honda.com

The Honda FCX Clarity is an electric powered car powered by a fuel cell running on hydrogen. It therefore rejects only water but its overall record is not that interesting (see below).

It is derived from the "Honda Accord Hybrid" series with a fuel cell type V Flow 1.



It is a car to places 5, 5 doors, available in limited production since June 2008 Japan and the United States.

Introduction

A fuel cell transforms hydrogen into electricity with an efficiency of about 40% or more.

Hydrogen is stored on the FCX under high pressure in a special tank. It is therefore necessary to supply hydrogen (which does not run the streets for now).
Only 4.1 kg (equivalent to 15,2 L petrol) hydrogen stored at 350 bars.
But because of high conversion yields, these 4,1 kg allow a still high autonomy of about 450 km.



Either an equivalent "virtual" gasoline consumption of 15,2 / 4,5 = 3,38 L / 100.

But the reality is less interesting because you have to take into account the energy costs of the synthesis and transport of hydrogen does not exist naturally.

For gasoline and diesel also (say purists) but their gray energy is between 10 and 20% of their own energy. Whereas for hydrogen it's more. The same applies to releases that are ultimately only "moved" from the car to the hydrogen generation unit.

Hydrogen cars are not nearly as clean as the prospectus would have us believe, but
look in more detail this FCX is still interesting technologically.

The fuel cell Vertical Flow (V Flow)

V flow fuel cell

This Honda vertical flow fuel cell is "revolutionary". The vertical design allows greater efficiency and compactness, there is more space in the living space and under the hood. So Powertrain technology can be used on the Clartity.

How the V Flow

A fuel cell produces electricity in the vehicle. It transforms the hydrogen stored on board in electricity by oxidizing it with oxygen in the air. The electricity powers the electric motor and a battery (optional). The only products of the reaction are heat and water.

The fuel cell used is a cell membrane which separates protons electrons. Several hundred membranes are combined in series.

1. The H2 arrives anode side in the fuel cell, using a catalyst (platinum), hydrogen is cracked into electrons and protons.
2. The electrons are routed through a circuit to generate electricity.
3. The protons pass through the membrane polymer.
4. Oxygen (air) between the cathode side and combine with the electrons and protons to form water.

Advances in fuel cell accelerated sharply since Honda launched its program.

Motor fuel cell

The FXC Clarity is currently offered exclusively leased to $ 600 / 450 months approximately € / month.
