- An advanced multifuelled solid oxide fuel cell (ASOFC) with a functional nanocomposite was developed and tested for use in a polygeneration system. Several different types of fuel, for example, gaseous (hydrogen and biogas) and liquid fuels (bio-ethanol and bio-methanol), were used in the experiments. Maximum power densities of 1000, 300, 600, 550 mW cm−2 were achieved using hydrogen, bio-gas, bio-methanol, and bio-ethanol, respectively, in the ASOFC. Electrical and total efficiencies of 54% and 80% were achieved using the single cell with hydrogen fuel. These results show that the use of a multi-fuelled system for polygeneration is a promising means of generating sustainable power.

- 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 cm2 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.
