Fuel cells convert hydrogen into electricity through an “electrochemical process”
2H2 + O2 -> 2H2O,
+ Electricity
+ Heat
Hydrogen Fuel Cell Basics
Very Quiet!
No Exhaust!
Very Efficient!

Fuel Cell Stack
Typically, stackcomposed
of 100s of cells
HydroGen3’s stack puts out
94,000 Watts
of electrical power

Shell Hydrogen Station in Washington DC
First
retail station in the
nation
to offer both gasoline
& hydrogen
The Benning Road Station
• Five Year GM–US DOE $88 Million Fuel Cell Vehicle and Infrastructure Demonstration Program

US Mail delivery in Washington, DC area (2004-06) 497,122 pieces of US Mail delivered in the first 19 months of the Program
GM – Government Demo Programs
• GM also has programs with the US Military, and has just concluded one with DC DOT
EPA Demo Program (2005-06)

Petroleum Dependence Trade Balance
Global Climate Change (CO2)
Local Air Quality
PM, HC, CO NOx, SOx

Cost (of the fuel cell system)
Hydrogen storage (since that determines driving range)
Commercialization Challenges(it does no good if we can’t sell in high volumes…)
“Infrastructure” (namely, where do I refuel?)
20
- 0 to 60 mph < 10 seconds- 300 mile range- 10,000 PSI compressed H2
- By-wire controls- electric all-wheel drive- 11 inch “skateboard”

So, you see, in addition to being COMPLETELY CLEAN and VERY EFFICIENT, Hydrogen & Fuel Cells can also lead to
VERY EXCITING new vehicles !!
