Solid oxide fuel cells (SOFC) are considered as one of the most adaptable technologies in terms of efficiency, flexibility, and environmental friendliness, and sorption-enhanced propane partial oxidation can improve hydrogen production and reduce carbon dioxide emissions.
Solid oxide fuel cells (SOFC), as high-temperature fuel supply systems, are regarded as one of the most adaptable technologies in terms of efficiency, flexibility, and environmental friendliness. Catalytic pro-pane partial oxidation is recognized as an efficient gas supply method for SOFC applications. However, incombustible by-product CO2 would decrease the purity of hydrogen, thereby reducing the power of fuel cells. Sorption-enhanced propane partial oxidation is an efficient way to adapt to SOFC operating conditions while improving hydrogen production and reducing carbon dioxide emissions. This paper introduces a cage-like porous Ce1-xCaxMO3-lambda, (M 1/4 Co, Fe and Cu) sorbent for providing high carbon dioxide sorption capacity and improving hydrogen purity over the Ni/Al2O3 catalyst. As obtained, Ce1-xCaxFeO3-lambda, and Ni/Al(2)O(3 )sorbent-catalyst performed the best, with the highest hydrogen yield up to 1654 mmol/g(cat).s which was 1055 mmol/g(cat.)s higher than that of pure Ni/Al2O3. The produced reforming gas is served as a fuel in the proposed SOFC system. A maximum output power density of 581 mW/cm(2) was reached. This work offered a simple and viable way of combining inexpensive and robust catalyst-sorbent for sorption-enhanced propane partial oxidation in terms of efficient indirect hydrogen supply toward SOFC power generation.
