What is “Project Driveway?”<br />The world’s first large-scale, real-world demonstration of<br />Fuel Cell Electric Vehicles (FCEV).<br />Comprised of 100+ FCEVs deployed in areas with existing hydrogen infrastructure (Southern California, New York, Washington, DC, Berlin) <br />Participants include:<br />The general public (i.e., Mainstream Drivers)<br />Public policy makers and organizations<br />Businesses<br />Media<br />Celebrities<br />2<br />
The Purpose of “Project Driveway?”<br />Real-World Data<br />To understand performance, durability, and reliability of fuel cell vehicle technologies in a real-world setting before FCEVs come to market<br />Driver Feedback<br />All elements of the driving experience, including vehicle performance, fueling, and lifestyle fit<br />Learnings <br />Data are already influencing engineering, marketing, and research and development as GM continues to develop future electric vehicles <br />3<br />
Where Are We Now?<br />To-date, in 24 months GM’s FCEV fleet has accumulated<br />1.3 million miles<br />4<br />
How Does A Fuel Cell Work?<br />A fuel cell generates electricity through an electrochemical reaction between hydrogen and oxygen<br />5<br />
GM Fuel Cell Electric Vehicle<br /><ul><li>Electric motor traction system provides vehicle with instantaneous torque, smooth acceleration, and quiet performance.
An electric vehicle powered by GM’s fourth-generation fuel cell system.
Durable to temps > 5 ºF</li></ul>GM’s FCEV was honored with the Green Car Journal's 2008 Green Car Vision Award®<br /> Awarded over several nominees including the Honda FCX Clarity and Toyota Prius Plug-In<br />
Power Management Distribution (PMD) (top)<br />Fuel Cell Stack (bottom)<br />Compressed Hydrogen Storage Tanks (3)<br />High-Voltage Battery Pack<br />Three-Phase AC Motor with Gear Reduction<br />Heat Exchangers (3)<br />(one in center, two at each corner)<br />
Why Fuel Cells?<br />Twice as efficient as gasoline engines<br />(Twice as far on the same amount of energy)<br />Water vapor is the only emission<br />A fuel cell vehicle is an electric vehicle (not a hybrid)<br />(Better performance than most cars)<br />Peak Power: 94 kW<br />Continuous: 73 kW<br />Torque: 236 lb-ft (320 N-m)<br />Allow extended ranges and quick fill-ups for an electric vehicle<br />(About 4-5 minutes to fill up)<br />
What’s Ahead?<br /><ul><li>Half the size (~size of a 4-cyl engine)
Uses about a third of the platinum</li></ul>9<br />
What’s Ahead?<br />The 30-month demonstration program GM committed to is winding down.<br />GM will keep upgrades of these vehicles running and will continue learning while it focuses on production-intent program for 2015<br /><ul><li>Some of the 119 FCEVs will receive hardware and software upgrades, part of a technology demonstration program with the U.S. Department of Energy.
Others will be used to continue showing that, with proper fueling infrastructure, hydrogen fuel cells are a viable alternative to gasoline-powered vehicles.</li></ul>GM will continue to use the Project Driveway fleet strategically to advance:<br /><ul><li>Fuel cell technology
Summary<br />Significant real-world lessons from FCEVs and Project Driveway drivers<br />1.3-million miles in about 24 months <br />Substantial progress being made toward production-intent fuel cell system<br />With proper fueling infrastructure, hydrogen fuel cells are a viable alternative to gasoline-powered vehicles<br />11<br />
