2.2: Study and discuss heat potential of fuel cell (page 34)

What is the maximum amount of energy that we can extract from a fuel?

How do you drive equation 2.29? What is its meaning?

2.2.1 How can you calculate reaction enthalpies? Discuss example -2.1

2.2.2 How enthalpy depends on temperature?

2.3 How work potential of the fuel cell depends on Gibbs Free energy? Discuss example 2.2.

What is water gas shift reaction and how does it relate to fuel cells?

2.3.2 Describe the relationship between Gibbs Free Energy and Electrical Work? Can you define a relationship between iheat enthly and electrical wor?

2.3.2 What is the relation between Gibbs free energy and reaction kinetics? Why diamond do not become graphite.

2.3.4 Describe the relationship between Gibbs free energy and voltage? Can you also imagine a relation between heat enthalpy and voltage?

2.3.5 What is standard electrode potentials. Discuss the example of hydrogen oxygen fuel cell. Just by comparing the standard reduction potential can you tell if iron will oxidize in the presence of hydrogen gas. Discus example 2.3
