    • There is provided a reformer for a fuel cell system, the reformer comprising: a reforming unit having a reaction substrate in which a catalyst layer is formed in a plurality of flow channels for allowing fuel to flow and for generating hydrogen through a reformation reaction of the fuel using thermal energy. When viewing a cross-section perpendicular to the flow direction of the flow channels, the reaction substrate defines each flow channel by a bottom portion and a pair of wall portions extending from the sides of the bottom portion, and a joint between the bottom portion and the wall portion is formed in a rounded shape. There is also provided a method of manufacturing a reaction substrate used for a reformer for a fuel cell system, the method comprising: (a) preparing a substrate; (b) anisotropically etching the upper surface of the substrate and forming a channel pattern of which a bottom portion and a wall portion are perpendicular to each other; (c) isotropically etching the channel pattern and forming a flow channel of which the joints between the bottom portion and the wall portions are rounded; (d) forming a support layer on the surface of the flow channel; and (e) forming a catalyst layer on the support layer.
    • 提供了一种用于燃料电池系统的重整器,重整器包括:重整单元,具有反应基板,其中催化剂层形成在多个流动通道中,用于允许燃料流动并通过重整反应产生氢气 燃料使用热能。 当观察垂直于流动通道的流动方向的横截面时,反应基板由底部和从底部的侧面延伸的一对壁部分以及底部和 壁部形成为圆形。 还提供了制造用于燃料电池系统的重整器的反应基板的方法,该方法包括:(a)制备基板; (b)各向异性蚀刻基板的上表面并形成其底部和壁部彼此垂直的通道图案; (c)各向同性地蚀刻通道图案并形成底部和壁部之间的接合处圆形的流动通道; (d)在流动通道的表面上形成支撑层; 和(e)在载体层上形成催化剂层。
