Abstract

A fuel cell system includes: a reformer for generating hydrogen from hydrogen-containing fuel; at least one electricity generator for generating electric energy through an electrochemical reaction of hydrogen and oxygen; a fuel supply unit for supplying the fuel to the reformer; and an oxygen supply unit for supplying the oxygen to the reformer and the at least one electricity generator. The reformer includes: a plurality of reaction sections, wherein at least one of the reaction sections has a channel; at least one cover plate; and a bonding joint between two of the reaction sections and between the at least one of the reaction sections and the at least one cover plate to couple the at least one of the reaction sections and the at least one cover plate to each other.

Description

technical field [0001] The present invention relates to a fuel cell system, and more particularly to a coupled structure of a plate type reformer for a fuel cell system. Background technique [0002] As is well known, a fuel cell is a power generation system that directly converts chemical reaction energy of oxygen and hydrogen contained in a hydrocarbon material such as methanol, ethanol, or natural gas into electrical energy. [0003] Recently, a polymer electrolyte membrane fuel cell (hereinafter referred to as PEMFC) having excellent output characteristics, low operating temperature, and quick start-up and response characteristics has been developed. PEMFCs have a wide range of applications, including mobile power supplies for vehicles, distributed power supplies for homes and buildings, and small power supplies for electronic devices. [0004] A fuel cell system using the PEMFC scheme includes a stack, a reformer, a fuel tank, and a fuel pump. The stack constitutes th...
