Aprilia have been working on fuel cell technology
for several years, and last week in Hanover they, together with
Swiss electric and fuel cell component manufacturer MES-DEA, showcased
their latest fuel cell scooter prototype, the Aprilia Atlantic Zero
Emission.
The advanced model is equipped with a 6kW (about
8hp) PEM fuel cell which is fitted, together with the hydrogen storage
and electrical engine, in the normal engine compartment of the scooter.
A top speed of around 85km/h can be achieved and the riding range
is up to 140km.
What are fuel cells?
We can all remember our school electrolysis experiments.
Or can we?? You know, the one where you run a current though a cathode
and anode in a beaker of water, generating oxygen from one and hydrogen
from the other. Or in other words, apply an electrical current to
H2O and get out O2 and H2.
Well, fuel cells are simply devices that reverse
this process, so you put in hydrogen from a fuel tank, oxygen from
the air and get out electrical power and water.
Why are fuel cells so important?
The only by-product of the fuel cell operation itself
is water; no pollution at all.
Hydrogen can be produced anywhere where there's
a supply of electricity and water by using electrolysis. If that
electricity comes from a renewable source such as the sun or wind,
then you have a totally pollution free method of power production.
Fuel cells will be found in all sorts of places
from video camera batteries to power stations. We'll have solar
tiles on our roof, an electrolyser in our attic and we'll use the
resulting hydrogen to heat and light the house as well as filling
up our motorcycle or scooter.
Politically, fuel cells eliminate economic dependence
on unstable oil producing countries (would we have gone to war in
Iraq now if we already had them?)
Fuel cells are more efficient (40%) than other internal
combustion engines (15%)... and they're silent.
So, why aren't they everywhere yet?
Fuelling fuel cells is still a major problem as
the infrastructure for production, transportation, distribution
and storage of hydrogen is not yet in place.
There's nothing inherently expensive about fuel
cells, but currently the components are essentially hand-made making
them far too expensive for mass appeal. Without mass production
the technology can't take off. Government funding/legislation and
niche markets should help to prime the transition.
Aprilia are looking to these niche markets for the
Atlantic Zero Emission. City congestion charging systems are likely
to proliferate after the success in London, where zero emission
vehicles are exempt not only of the charge, but also national road
tax, as well attracting free on road parking. OK, ALL motorcycles
and scooters are exempt in the London experiment, but that has more
to do with the front number plate reading camera charging technology.
Don't expect other schemes to show such benevolence to internal
combustion engine 2-wheel transport.
The military also like them because of their low
heat signature and silent operation. Perhaps the SAS could soon
be going into battle on Aprilia Atlantics..
