Abstract
The present invention provides a fuel cell system that comprises a stack that generates electricity through a reaction between hydrogen and oxygen and a fuel processing device that is connected to the stack to generate the hydrogen from fuel and supplies the hydrogen to the stack. It further comprises a fuel supply unit that supplies the fuel to the fuel processing device and an air supply unit that supplies air to the stack and the fuel processing unit, respectively. The fuel processing device comprises a first reformer that generates byproducts along with the hydrogen through an electrolysis reaction of the fuel using electric energy and a second reformer that generates the hydrogen through a reformation reaction of the fuel using thermal energy.
