Solid oxide fuel cells (SOFCs) are a green energy technology that offers a cleaner and more efficient alternative to fossil fuels. The efficiency and utility of SOFCs can be enhanced by fabricating miniaturized component structures within the fuel cell footprint. In this research work, the parallel-connected inter-digitized design of micro-single-chamber SOFCs (µ-SC-SOFCs) was fabricated by a direct-write microfabrication technique. To understand and optimize the direct-write process, the cathode electrode slurry was investigated. Initially, the effects of dispersant Triton X-100 on LSCF (La0.6Sr0.2Fe0.8Co0.2O3-δ) slurry rheology was investigated. The effect of binder decomposition on the cathode electrode lines was evaluated, and further, the optimum sintering profile was determined. Results illustrate that the optimum concentration of Triton X-100 for different slurries was around 0.2–0.4% of the LSCF solid loading. A total of 60% of solid loading slurries had high viscosities and attained stability after 300 s. In addition, 40–50% solid loading slurries had relatively lower viscosity and attainted stability after 200 s. Solid loading and binder affected not only the slurry’s viscosity but also its rheology behavior. Based on the findings of this research, a slurry with 50% solid loading, 12% binder, and 0.2% dispersant was determined to be the optimal value for the fabricating of SOFCs using the direct-write method. This research work establishes guidelines for fabricating the micro-single-chamber solid oxide fuel cells by optimizing the direct-write slurry deposition process with high accuracy.

A novel micro-solid oxide fuel cell (µ-SOFC), with a rectangular saw-tooth shape, was designed with a 50 wt% BYCF + 50 wt% GDC 10 cathode and a 60 wt% NiO + 40 wt% GDC 10 anode deposited on a GDC 10 electrolyte substrate by the spray pyrolysis technique. µ-SOFC receives methane only (CH 4) as fuel gas from one side. The fuel gas was applied at a flow rate of 0.2 l min −1. The power density obtained was 1.0 µW at 800 • C. Voltage levels generated by the µ-SOFC at 40-99.99% CH 4 was highly accurate representing the quantity of CH 4. Low accuracy was observed at 10-30% of CH 4. Therefore, µ-SOFC is an application of SOFC technology to be a sensor for economically detecting CH 4 in a biogas system, while being capable of operating in humid conditions at high temperatures.
