Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Flow‐through type tubular solid oxide fuel cells were successfully fabricated and operated with a single‐chamber configuration for realizing the simultaneous generation of electric power and synthesis gas from methane by integrating a downstream catalyst into the fuel cell reactor. A new operation mode, which completely eliminated the gas diffusion between cathode side and anode side, is proposed. The cell showed high open‐circuit voltages of 1.02–1.08 V at the furnace temperature range of 650–800°C when operating on CH₄‐O₂ gas mixture at a molar ratio of 2:1. A peak power density of approximately 300 mW cm⁻² and a maximum power output of 1.5 W were achieved for a single cell with an effective cathode geometric surface area of 5.4 cm² at the furnace temperature of 750°C. The in‐situ initialization of the cell using CH₄‐O₂ gas mixture was also realized via applying an effective catalyst into the tubular cell. © 2013 American Institute of Chemical Engineers <italic>AIChE J</italic>, 60: 1036–1044, 2014</p> </abstract>
