 | Overview | Solid oxide fuel cells (SOFC), operating at temperatures around 1000oC, are power generators capable of converting the chemical energy of a fuel into electrical energy and with a high temperature thermal by-product. We are currently using kinetic measurements combined with steady state and transient electrochemical techniques, mainly AC impedance Spectroscopy, in order to investigate the parameters affecting the catalytic and electrocatalytic activity of anodes in internal reforming solid oxide fuel cells. In these systems the fuel (methane or natural gas) is cofed with steam and reformed over the catalytic anode producing CO and H2 that can be further readily oxidized electrochemically on the anode for electricity production. Internal reforming leads to significant cost reduction (up to 30%) of the fuel cell plant and to increase of the overall efficiency of the process.
Also, fuel cells permit the direct conversion of a significant portion of the Gibbs free energy change of exothermic reactions into electricity rather than heat. We are currently investigating the development of new electrocatalytic anodes for the simultaneous production of valuable chemicals and electrical energy (chemical cogeneration). Parallel studies focus on the utilization of the NEMCA effect in aqueous electrochemistry. |
