The term “irreversible losses” is used to summarize the major effects that lead to a deviation of the observed cell voltage compared with the value calculated from thermodynamic theory. The aim of this chapter is to serve two purposes. First, an overview of the main loss mechanisms coming from electrode kinetics, ohmic resistance, and mass transport is provided. Second, this chapter demonstrates how the underlying physical model in our mind influences the method and result of calculations. Throughout the chapter, several modeling approaches are compared, and their implications on the model parameters are discussed. This is of great practical importance for the interpretation of experimental work and the comparison with literature data. The examples describe the performance of half cells, single cells, and fuel cell stacks. |
