The GM Hydrogen4 minivan is the next generation fuel cell vehicle from General
Motors that one-ups the Hydrogen3 minivan. The GM Hydrogen4 was
rolled out in Germany as part of the company's Project Driveway
GM HydroGen 3 Minivan
The GM Hydrogen4 uses a 440-cell fuel cell stack,
73 Kw electric motor and has three carbon fiber hydrogen tanks
that help propel the vehicle to a range of around 200 miles. The
GM Hydrogen4 has a top speed of around 100 mph. The GM Hydrogen4
is also based upon the Opel Zafira like the Hydrogen3 vehicle.
General Motor's HydroGen3 vehicle is the last general fuel cell
vehicle that marked yet another milestone for GM in regards to pursuing
a lineup of greener vehicles. The GM HydroGen3 is an environmentally
friendly fuel cell minivan that has been used by FedEx as a delivery
vehicle for real world testing trials.
According to Raymond Grigg Chairman and CEO of the Japan division
of General Motors, "To really prove that fuel cell vehicles
are equal to or better than conventional, internal combustion
vehicles, you need to operate them under tough, every-day conditions.
Our fuel cell technology has advanced to the point where it's
important to involve a real heavy-duty commercial user in our
research and development activities. We expect to learn a lot
by having FedEx Express put our HydroGen3 to the test on their
daily delivery runs on the streets of Tokyo. This is how you truly
prove durability and dependability."
The HydroGen3 is designed based on the Opel Zafira MPV. Packed
with more power then HydroGen1, and the latest of the HydroGen
series, GM HygroGen3 has a simpler start up procedure and a more
compact fuel cell stack. Not exactly a racecar (though it did
participate in the Monte Carlo Rally), the HydroGen 3 accelerates
from 0 - 60 mph in approximately 16 seconds. It has a top speed
of 100 mph, which is respectable enough. The GM HydroGen 3 is
powered by a 60 kW / 82 PS three-phase asynchronous motor. GM
is testing both liquid hydrogen and compressed hydrogen storage
systems with the HydroGen3.
The GM Hydrogen 3 has the same 5-seating capacity as the Opel Zafira
and has participated in various demonstration projects around the
world including Berlin, Germany. Two of the breakthroughs for the
HydroGen3 has been the elimination of a buffer battery found in
early versions to deal with peak electrical usage and a method for
humidifying the fuel cell stack.
Here are some facts about the HydroGen3:
- Five seat, front wheel drive
- Fuel cell propulsion system packed as a single unit
The fuel cell propulsion system has:
- 200 individual fuel cells wired in a series
- Self humidifying stack
- Continuous output : 94 kilowatts
The liquid hydrogen storage system of the GM HydroGen3 is equipped
- vacuum insulated stainless steel tank
- capacity: 4.6 kilograms of liquefied hydrogen (temperatures
of minus 253 degrees C )
- driving range : 250 miles
Compressed 700 hydrogen tanks have the following features:
- Two carbon composite tanks
- Service pressure: 10,000 psi
- Capacity: 3.1 kilograms of compressed hydrogen
- Driving range: 270km (170 miles)
The GM HydrogeGen3 was the first hydrogen fuel cell vehicle certified
by the Japanese government for operation on regular roads. Another
joint venture GM has for the GM HydroGen3 is with Shell. It's
two year program is being conducted in Washington DC giving the
Members of Congress the chance to test drive the fuel cell vehicles.
The US Postal Service also is using the GM HygroGen3 mini-van
to deliver mail in and around the Washington DC area.
