Abstract

Reversible solid oxide cell (rSOC) and solid oxide electrolysis (SOE) are gaining growing interest because they can convert both electricity into a chemical fuel and fuel back to electricity with high efficiency. This work summarizes the electrochemical performance characterization of Elcogen E350 stack both in fuel cell and electrolysis modes. Elcogen E350 stack is composed of 15 unit layers all having a 121 cm2 active electrode area. The electrochemical characterization is conducted in temperature region 650-700 °C and with varying current densities, multiple hydrogen-to-steam ratios, reactant utilizations and air flow rates. Results indicate that the stack can be used not only as a fuel cell but also in electrolysis mode. It is capable to be operated up to 1.0 A cm-2 current below 700 °C and can be operated also with high reactant utilization in electrolysis mode.
