With oil prices going through the roof,
following the unsuccessful War on Weapons of Mass Destruction,
fuel cells are back in the news (we know the WMD’s are there
somewhere, we just haven’t found them yet, but after we bury
some we’ll dig ‘em up again and show the world how clever
we are).
Hyundai (HMC) are next in the fuel-cell
vehicle push, and claim they will have a fuel cell vehicle
(FCV) on sale by 2010. What is more, they will have a
petrol-electric hybrid car available for commercial sale
within two years.

According to the GoAuto website, the senior
vice-president of Hyundai-Kia’s Advanced Technology Centre,
Joon-Chul Park, said that both hybrids and fuel cell vehicles
were crucial elements in the South Korean car-maker’s quest
to become one of the five biggest auto manufacturers by 2010.
He said commercialization would be realized
at the end of each respective R&D program, which with the
petrol-electric drive-train focuses on the Getz small car and
for fuel cells has switched in recent months from the ageing
Santa Fe to the all-new Tucson all-terrain wagon.
These platforms will change before hitting
the streets, but Park confirmed that a SUV (sports utility
vehicle) platform would be used for the first commercial fuel
cell vehicle when the current Tucson program ends in 2009.
“The five years (from 2004) is our
demonstration and development period, so we’d have cars for
commercial sale from 2010,” Park told GoAuto at the
Tucson’s launch in South Korea last month.
“The vehicle will change. The Tucson is
the platform for development for this first technology. At
that time, we may choose a different platform (but) we think
SUV is the proper platform we ought to use at that time.
Packaging is the dominant issue. SUVs give us more space than
other vehicles.”
Park said HMC had not set out to become the
first car company to offer mass-market fuel cell vehicles but
was determined to run with leaders in the field such as Toyota
and Honda. “The fuel cell will be the future power-train so
somehow we have to stay with the development of fuel cell
technology,” he said.
Unveiled at the Geneva motor show earlier
this year, the front-drive Tucson FCV is HMC’s second
generation zero-emissions vehicle built in collaboration with
American fuel cell giant United Technologies Corporation
(UTC).
It has several advantages over the previous
Santa Fe FCV including cold-weather starting, a higher-output
fuel cell stack and an extended driving range from the Dynetek
developed hydrogen storage tank. Vehicle durability and
interior packaging (lower floor height) are also improved with
the stack relocated from the undercarriage to the traditional
engine bay.
“Once we put the fuel cell stack under
the floor, we became worried about the damage that could
happen when driving the vehicle on the road,” Park said.
“If it’s on the floor, naturally it’s more susceptible
to rust and those kinds of things, so we have put it in the
engine bay to better protect it.”
HMC also claims to have eliminated
hesitation associated with power being cut when the Santa Fe
FCV is driven under hard acceleration, the biggest sticking
point to emerge at a 1000m straight-road drive given to
journalists at HMC’s Namyang R&D centre near Seoul.
“(Santa Fe) is operating between 160-270
voltage but Tucson’s average voltage is more than 300V, so
higher voltage gives us better motor performance and some more
room not to have that hesitation,” said Hyundai-Kia
principal research engineer (fuel cell), Tae Won Lim.
“The second reason is that in order to
improve the fuel cell durability, we have done so much
research and development that Tucson’s durability is three
times longer than Santa Fe.”
The Tucson FCV will be tested in real-world
conditions, with at least 30 Tucson FCVs based in California
over the next few years. The latter could increase now that
HMC, along with several other manufacturers, has secured a
slice of a USD 350 million US Government grant designed to get
more FCV prototypes onto American streets.
HMC claims it will spend USD 2.3 billion on R&D in
2004, almost double its expenditure in 2001, which in addition
to fuel cell and hybrid power trains will be used for
stand-alone internal combustion engine developments including
a forthcoming common-rail turbo-diesel that meets Euro 4
regulations.
