BMW & Delphi Present the First Development Vehicle
Equipped With a Solid Oxide Fuel Cell
MUNICH, Germany, Feb. 16 The first development vehicle to
be equipped with a Solid Oxide Fuel Cell (SOFC) was unveiled in Munich today
by BMW and Delphi Automotive Systems . After nearly two years of
the companies working closely together on the groundbreaking program, the
vehicle has operated and shown encouraging results.
"Both BMW and Delphi have considerable expertise in providing high-
technology solutions to meet environmental issues," said Jose Maria Alapont,
president of Delphi Europe-Africa-Middle East and a vice president of Delphi
Automotive Systems Corporation. "There are many synergies between our
companies that allow us to efficiently work together to develop outstanding
new technologies."
The development vehicle uses the SOFC as the key component in an Auxiliary
Power Unit (APU), which could generate electrical energy for a wide range of
potential vehicle systems and allows for the addition of further electrical
features. The SOFC / APU provides sufficient energy for existing
mechanically-driven sub-systems, such as the airconditioning and water pumps,
to be driven electrically. This allows for more efficient operation and
provides a much higher level of control.
Explaining his company's strategy, Dr. Burkhard Goeschel, BMW board member
responsible for development, said: "Generator outputs have had to go up by
about 30 percent and battery capacities by about 200 percent in the last 30
years. If we reflect that before long our cars will have electric water
pumps, electric power steering and electrically actuated brakes as well as the
whole range of modern communication equipment, then we must expect current
consumption at least to double again in coming years."
Using a conventional, mechanically driven generator, supplying 1kW of
electricity requires around 1.5 litres of fuel per hundred kilometres. Using
the first production SOFC / APU will cause a reduction of 46 percent, leading
to substantial fuel economy and environmental benefits. Delphi is working
with BMW to bring the system to market in a passenger car.
Another important use of the APU will be to provide more power than can be
reasonably supplied by a battery when the vehicle's engine is switched off.
This may be to heat or cool the cabin while the driver is still eating
breakfast when stuck in traffic. In commercial vehicles, an APU could be used
to run refrigeration units or airconditioning while the vehicle is parked
overnight or stopped for deliveries. Delphi is developing reformers that can
convert either diesel or gasoline into hydrogen to fuel the APU.
"This is a major breakthrough technology to help protect our environment,"
concludes Jose Maria Alapont. "Delphi has a complete portfolio of
environmentally-friendly vehicle systems including both gasoline and diesel
Engine Management Systems, 42-Volt system architectures, fluid-free electric
steering, electric braking systems and recyclable interior products."
