A critical factor hampering the deployment of fuel-flexible, low-temperature solid oxide fuel cells LT-SOFCs is the long-term stability of the electrode in different gas environments.

Higher energetic density, better resistance to thermal stresses, and smaller starting times as compared with conventional planar stacks, make the so-called microtubular SOFC mT-SOFCs with diameters in the millimeter size region devices suitable for portable applications in the sub kilowatt energy range. However, fabrication of mT-SOFCs is a challenging process, where a number of ceramic layers with different compositions and characteristics have to be placed together in the cylindrical device. Several co-sintering processes have to be performed at different temperatures and using distinct atmospheres to complete cell fabrication. High temperature ceramic solid oxide fuel cells SOFCs are well-known electrochemical devices that directly convert, in a very efficient way, the chemical energy of hydrogen-enriched fuels, including hydrocarbons, into electricity and heat power Singhal and Kendall, ; Cooley, They are promising energy conversion devices due to their fuel flexibility, good electricity generation efficiency, and high efficiency for total power generation.

Advanced anodes for high-temperature fuel cells

The paper aims to present the innovative design of a planar multilayered high temperature solid oxide fuel cell SOFC , which is easy to manufacture, and features high resistance to rapid temperature changes. Temperature resistance was accomplished thanks to easy to heat, thin flat ceramic structure of the cell and elimination of metallic interconnections. Two networks of fuel distribution microchannels are engraved on both sides of the anode laminate. Tests show that the stack is resistant to the rapid temperature change. Multiple cycling does not destroy the stack.

Over the past one decade, several cell component materials and their combinations have been attempted to match with the appropriate requirements of solid oxide fuel cells SOFCs. A large number of cell component materials with superior properties have been developed.
