The main properties of the fuel cells based on polymeric electrolyte are described in this chapter explaining the technical reasons that make them more suitable to automotive applications in comparison with other types of fuel cells. A preliminary discussion on basic thermodynamic and kinetic concepts necessary for the comprehension of fuel cell electrochemistry is presented before describing details and problems of the different components of a polymeric electrolyte fuel cell: membrane electrolyte, electrocatalysts, gas diffusion layers, bipolar plates. The effect of different operative parameters (membrane humidity grade, reactant pressure, stack temperature, stoichiometric ratio) on stack performance is experimentally analyzed, evidencing the kinetic limitations which cause efficiency losses. A brief discussion on stack durability issues concludes the chapter.
