Demonstration of hydrogen production in a hybrid lignite-assisted solid oxide electrolysis cell

A Ni-YSZ/YSZ/Ag–Pt cell was used to demonstrate the concept of high temperature lignite-assisted electrolysis in hybrid (combined solid oxide and molten carbonate) operation. To assess the performance of the hybrid concept, the same cell was also used for lignite-assisted electrolysis in absence of an anodic carbonate load, as well as for fuel cell measurements using H2 and lignite as fuels, the latter both with and free of molten carbonates.
