Solid Oxide Cell is an electrochemical energy conversion technology with the great advantage of dual operation as Solid Oxide Fuel Cell (SOFC) and Solid Oxide Electrolyzer (SOE). For that, this technology is defined as "reversible". However, due to the consequences of frequent inversions from SOFC to SOE (and vice-versa), the complete reversibility and efficiency may be attempted after a finite number of operation cycles. This paper presents experimental outcomes to evaluate the impact on performances of two of the primary process variables, i.e., SOFC/SOE commutation frequency and reactant gases utilization rates. All tests are performed over 500 hours.

Abstract
Solid Oxide Cell is an electrochemical energy conversion technology with the great advantage of dual operation as Solid Oxide Fuel Cell (SOFC) and Solid Oxide Electrolyzer (SOE). For that, this technology is defined as "reversible". However, due to the consequences of frequent inversions from SOFC to SOE (and vice-versa), the complete reversibility and efficiency may be attempted after a finite number of operation cycles. This paper presents experimental outcomes to evaluate the impact on performances of two of the primary process variables, i.e., SOFC/SOE commutation frequency and reactant gases utilization rates. All tests are performed over 500 hours.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
