In this paper, the reaction rate of methane steam reforming over anode material was estimated to obtain the fundamental data for the analysis and the design of a solid oxide fuel cell (SOFC) with direct internal reforming. The cermet of Ni and yttria-stabilized zirconia (YSZ) was applied for the anode of SOFC. In the experiment, Ni/YSZ was used as a catalyst for methane steam reforming. The volume ratio of Ni to YSZ is 60% to 40% and the particle size was below 300 μm. A small tubular reactor, which was put inside an electric furnace, was employed, and the Ni/YSZ powder was put inside the reactor. Methane and steam mixture was supplied into the reactor. The composition of the dry gas after reforming was measured with a gas chromatograph equipment. Based on the experimental data, the turnover rate of methane was estimated. In addition, the pre-exponential factor, the activation energy and the reaction order were calculated, and therefore the reaction rate equation was obtained.
