In this article, a planar, low‐temperature, solid‐oxide fuel cell based on nanocomposite materials is developed by cost‐effective tape casting and hot‐pressing methods. First, a single cell with active area of 6 × 6 cm 2 was manufactured and tested to determine the cell performance. The power density of 0.4 and 0.7 W cm −2 were achieved at stable open‐circuit voltages at operating temperature of 550°C using the syngas and hydrogen, respectively. Based on these experimental results, a 5‐kW low‐temperature, solid‐oxide fuel cell polygeneration system is designed and analyzed. This system can provide electrical power and heating concurrently from a single source of fuel. The system design and the energy and mass balance are presented and a simulation based on syngas is performed. Finally, effects of fuel utilization factor, fuel cell operating temperature, and air temperature at cathode inlet on performance of polygeneration system is investigated.
