Slide 6: Why use a hydrogen fuel cell?
Why use a hydrogen fuel cell? Hydrogen and fuel cells Lower heating values (LHVs) of fuels JP-8 Jet-fuel gasoline • Hydrogen gas has the highest hydrogen (l) energy per unit weight (kilograms or hydrogen (g) pounds) ammonia • Combine with 50-60% efficient ethanol polymer fuel cell methanol butane (l
Slide 7: Fuel cell vs. battery
Fuel cell vs. battery High energy of H2 × high efficiency of fuel cell = long endurance • For smaller systems and short missions – batteries always preferred • Fuel cells scale better for larger systems

Slide 10: How hydrogen solves "the charging problem"
How hydrogen solves “the charging problem” • Battery electric vehicles take a long time to charge • Not only are the chemistries unstable during charging, but there is limited infrastructure. Hydrogen – 33,410 Watt hours per kg 2700 Watts per liter Need about 45,000 Watt hours of hydrogen to deliver
