ABSTRACT
The fuel cell as a power system contains multiple components besides the fuel cell unit. These include a fuel supply system that may contain a fuel processor and fuel conditioners, the reactant flow and conditioning system, waste effluent handling system, electrical power conditioning and delivery system, and thermal management system. In this chapter, these basic components of a fuel power system are discussed. The key fuel for the fuel cell, hydrogen, as an energy carrier is presented, where its generation, storage, delivery, and application are given in detail. For the fuel cell technology to mature, each of these components has to be economically viable and safe to use.
