This chapter provides a description of PEM fuel cell-based system. First, it shows the structure of a single cell, the advantages and disadvantages of this type of fuel cell, the expressions of the generated voltage and the efficiency, and the generic structure of a generation system based on PEM fuel cell. Second, the chapter provides a review of the principals models presented in the literature to describe the behavior of the system. It describes in detail the model used as a base to represent the system in the next chapters the book. Then, the described model is used to study the optimal operation of a the fuel cell at different loads, showing the  benefits of an optimal operation in terms of hydrogen reduction and greater peak power.
