ABSTRACT:
The invention relates to a solid oxide fuel cell having an inlet for fuel, an inlet for air, an outlet for product gas, an outlet for depleted air, a fuel flow path between the inlet for fuel and the outlet for product gas, an air flow path between the inlet for air and the outlet for air, and elements having an upstream part and a downstream part, wherein the upstream part has an anode layer, a cathode layer and an oxygen ion-conductive layer between the anode and the cathode layer, and wherein the downstream part has an oxygen ion- and electron-conductive layer. The invention further relates to a process for the generation of electricity and the production of carbon dioxide from a hydrocarbonaceous fuel using such a fuel cell.
