Yes, there are a couple of posts here on ecomodder that refer to this paper from 1977!

Alright, if you drive one hour at highway speed, youc car getting 30MPG or 7.8L/100 you would have used 2 gallons or 7.8L of fuel. at 12:1 air fuel ratio that should be 24 gallons of air, or 93.6L of air consumed with that fuel. It does not seem right, that amount of air does not sound right, but you cannot dispute the logic.
Hint:
Ideal A:F is closer to 14.7:1 and is mass. So 7.8 liters is 5.6 kg of gasoline (0.719 kg/l)
5.6 * 14.7 = 82.4 kg of air. Air weighs about 1.2g/l that's about 70,000 Liters of air... If the A:F for H2 is 2:1 you'd need 40 kg of H2 at 0.089 g/l that's about 449,438 liters. You might want to check your assumptions.
