Reduced resources of fossil fuel and increased demand, cost, and uncer-
tainty in the steady supply of imported oil have sparked the search for
alternative electric power generation systems. Additionally, there is an
increased global concern for the higher greenhouse gas emission and its
effect on global warming and the environment. A fuel cell power genera-
tion system is an attractive alternative to conventional power generation
systems such as steam-turbine thermal power plant and internal com-
bustion engine because of its higher efciency, improved fuel economy,
reduced dependence on conventional fuel, and lower emission of envi ...
