Solid oxide electrolysis cells (SOECs) and solid oxide fuel cells (SOFCs)

We study the performance of state of the art, industrial SOECs and SOFCs, under original off-design operative conditions, for applications in novel cycles for hydrogen production, syngas production, and power generation. Main focus is the long-term behavior (> 1500 h) of single cells with interconnectors, with attention to the optimization and preservation of the electrochemical performance. Analysis of the results with physical I/V and EIS models allows to ease the integration of the stack with the cycle’s balance of plant. The performance of single cells is also explored under pressurized conditions up to 30 bar.
