A connection structure between a fuel vaporizer and an oxidizer in a fuel reformer is disclosed. Fuel reformers having the connection structure may be included in fuel cell systems. Methods for forming the connection structure are also disclosed. The method includes forming the fuel vaporizer and forming the oxidizer. Forming the fuel vaporizer may include forming through-holes in a bottom panel and a top panel to form the fuel vaporizer, forming an inner side panel protruding in a direction substantially normal to a frame of the bottom panel through-hole and welding a top portion of the inner side panel to the frame of the top panel through-hole. Forming the oxidizer may include welding a top portion of an inner wall of the oxidizer to a bottom surface of the frame of the bottom panel through-hole.

An auto ignition type autothermal reformer (ATR) performs reproducible ignition using a catalyst that performs ignition without a separate ignition unit, such as an igniter or heating wire, and a fuel cell system having the ATR. The ATR includes a reaction container having a first opening through which a fuel is introduced into the reaction container and a second opening through which a reformate is discharged from the reaction container, the fuel having a mixture of an aqueous primary fuel solution and hydrogen peroxide; a first catalyst disposed adjacent to the first opening in the reaction container, the first catalyst being a granular catalyst; a second catalyst disposed at the rear portion of the first catalyst to promote an autothermal reforming reaction; and a third catalyst disposed at the rear portion of the second catalyst to promote an oxidation reaction.
