In this work, a new stabilized finite element algorithm, using a single domain approach for the solution of mass and energy transport phenomena in solid oxide fuel cells is presented. The proposed numerical procedure is based on the Artificial Compressibility (AC) Characteristic Based Split (CBS) scheme. The stability analysis carried out by the authors for the first time is based on the order of magnitude analysis of all the terms present in the conservation equations. The stability limits speed up the simulation process enormously. Furthermore, the single domain approach allows the application of the present method to the simulation of a whole cells stack.

Abstract
In this work, a new stabilized finite element algorithm, using a single domain approach for the solution of mass and energy transport phenomena in solid oxide fuel cells is presented. The proposed numerical procedure is based on the Artificial Compressibility (AC) Characteristic Based Split (CBS) scheme. The stability analysis carried out by the authors for the first time is based on the order of magnitude analysis of all the terms present in the conservation equations. The stability limits speed up the simulation process enormously. Furthermore, the single domain approach allows the application of the present method to the simulation of a whole cells stack.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
