Abstract
A fuel cell system includes: a reformer adapted to generate hydrogen from a fuel containing hydrogen through a chemical catalytic reaction using thermal energy; at least one electricity generator adapted to generate electric energy through an electrochemical reaction of hydrogen and oxygen; a fuel supply unit adapted to supply the fuel to the reformer; and an air supply unit adapted to supply oxygen to the reformer and the at least one electricity generator. The reformer includes a plurality of plates stacked with each other and forming at least one passage adapted to allow a fuel or a gas to flow therethrough and at least one catalyst layer coated on inner surfaces of the at least one passage. In the reformer, the at least one catalyst layer is formed to have a plurality of grooves extending substantially in a same direction as of the at least one passage.
