Abstract: Abstract A propane-fueled solid-oxide fuel-cell-based system is an extraordinary type of technology for stationary mobile power generation given that it offers higher efficiency, silent operation and clean conversion of hydrocarbon fuels. In this study, we designed and developed a 150 W-class tubular SOFC power-generation system integrated with a catalytic partial reformer (CPOX) for the propane fuel and heat exchangers with the goal of making a robust and compact system for portable power applications. Micro-tubular SOFC cells were fabricated by ceramic processing and the cells were assembled in the form of a short stack. The CPOX nano-catalyst CeO 2 Zr 2 O 3 /Pt supported on γ-Al 2 O 3 was prepared and tested for its propane-reforming characteristics under the present operating conditions. The CPOX catalyst was used in the integrated reformer, and the performance of the 150 W-class SOFC power-generation system operating on propane fuel was studied. The rapid startup and temperature sustainability of the short stack were also monitored and stable stack temperatures were achieved within 20 min. Long-term galvanostatic operation of the power-generation system was also conducted to investigate the durability of the system. This study confirms that propane-fueled robust and compact 150 W-class power-generation systems are suitable for portable applications and that the role of efficient CPOX catalysts is crucial for high performance of the stack when operating on propane fuel. Highlights • Propane-fueled 150 W-class SOFC power-generation system tested. • Compact integrated CPOX reformer and short-stack resulted into robust performance. • Pt/Ce Zr @γ-Al 2 O 3 catalyst for propane fuel performed best at C/O:0.6. • 30-cell micro-tubular SOFC system produced ∼150 W with stable operation.
