The cathode represents the main source of energy loss in hydrogen fed solid oxide fuel cells (SOFCs). In order to reduce the polarization resistance, porous composite cathodes, which consist of sintered random structures of electron-conducting (e.g., strontium-doped lanthanum manganite, LSM) and ion-conducting (e.g., yttria-stabilized zirconia,...

A steady-state mathematical model of charge and mass transport and electrochemical reaction in porous composite cathodes for solid oxide fuel cell application is presented. The model, based on local mass and charge balances, describes the domain as a continuum, characterizing kinetics as well as mass and charge transport using effective...
