AbstractIn this work the processing route for an anode supported microtubular solid oxide fuel cell is adjusted. The fuel cell composition and microstructure design is based on previous work. In this work we have developed microtubular cells based on an extruded support. Firstly, Ni-YSZ anode was manufactured by Powder Extrusion Moulding (PEM). Feedstock composition and extruding parameters were adjusted to obtain tubular green bodies. An YSZ layer was then deposited as the electrolyte and the sintering parameters were optimized to obtain a dense layer. An active area of ~1 cm2 LSMYSZ was deposited as the cathode and its electrochemical performance was measured using pure hydrogen as fuel, yielding a power output at 0.5V of 0.7Wcm-2 at 8500C.
