Abstract
The present invention refers to the conversion of gaseous or gasifiable fuels with high methane content, such as natural gas, biogas, synthesis gas or gas originated from various industrial process rejects, with or without prior desulfurization and elimination of other contaminants, in a solid oxide fuel cell (SOFC), with special anodes, based on mixed oxides or metal oxides with a perovskite type structure, either or not nano structured, into light hydrocarbons, primarily ethylene and ethane.
