Question

e) If one drives 2000 km per month and a gallon of methanol costs $1.20, determine the amount of fuel saved per year when you use the fuel cell version compared with the IC version?

f) For a ten year loan with yearly repayments of principal plus interest of 18% of the initial amount borrowed. By how much can the initial cost of the fuel-cell car exceed that of the IC car for one to break even? Assume that after 10 years the car is totally depreciated.

g) Determine the open circuit voltage of an ideal methanol fuel cell at RTP. To answer this question, make an intelligent guess about the number of electrons freed per molecule of methanol.
