Section 3. Essay (60pt)

Part A. Answer all question

A result of recent developments in fuel cell technology, serious consideration is given to direct alcohol fuel cells in which alcohol is used directly as the fuel. Methanol and ethanol are the most promising fuels for transportation applications. To assess the environmental benefits of these fuel choices over petroleum, it is important to analyze their energy uses and emissions during the fuel cycle. Evaluation of greenhouse gas emission is being taken in to consideration in order to evaluate the efficiency of each type of fuel cells. In this experiment only, CO2 was used as a variable. Amount of CO2 in grams per kilometer of driving is used as a unit of measurement.
