GM's global commitment to developing transportation that reduces oil use and promotes energy diversity continued today at the Shanghai Auto Show with the unveiling of the next iteration of the E-Flex electric architecture, configured with GM's newest, most efficient hydrogen fuel cell system to date.
This second variant of the E-Flex system uses GM's new fifth-generation fuel cell propulsion technology and a lithium-ion battery to provide up to 483 km of petroleum- and emissions-free electric driving. The fuel cell E-Flex is a true Zero Emission Vehicle (ZEV) and operates all-electric from both hydrogen fuel cell-generated electricity and grid electricity. It is plug-in capable, adding up to 20 additional miles (34 km) each time it is charged, further reducing trips to the refueling station.
"The beauty of our E-Flex strategy is that it allows us to package various propulsion systems into the same space depending on what energy is available locally," said Larry Burns, GM's vice president of Research and Development and Strategic Planning. "It also provides flexibility in the sources of energy. We can obtain hydrogen or electricity from a myriad of renewable sources – wind, solar, geothermal, hydroelectric and biofuels – or from traditional sources such as natural gas, clean coal, nuclear or even gasoline."
Independent studies indicate hydrogen fuel cell vehicles offer superior overall efficiency and fewer greenhouse gas emissions compared to internal combustion engines running on gasoline, when considering both the creation of the energy and its use in the vehicle.
GM's fifth-generation fuel cell system is half the size of its predecessor, yet it provides the same power and performance. The fourth generation currently powers the Chevrolet Sequel concept vehicle. The Sequel stores 8 kg of hydrogen and delivers a range of 300 miles (483 km). The fuel cell Volt will also deliver 300 miles of range, but with only 4.0 kg of hydrogen (75 miles / kg).
"Our progress has made us increasingly confident that our fuel cell propulsion system will be automotive-competitive," said Burns. "But before this technology can be made widely available, governments, energy suppliers and infrastructure companies around the world need to collaborate with GM and the auto industry to develop a market for fuel cell vehicles and hydrogen fuel."
