One of the greatest technological challenges nowadays refers to the development of new power sources. Fuel cells have emerged as one of the alternatives gaining attention in recent years due to its high efficiency and low environmental pollutants production. In particular, solid oxide fuel cells (SOFC) have as main advantage to promote fuel internal reform with high energy conversion efficiency, not requiring the use of noble metals. The main challenge of SOFCs fed with biofuels is the carbon deposition on the anode, which causes poisoning and severe degradation of the SOFC performance. This project involves the preparation and physicochemical characterization of several bimetallic catalysts based on NiM (where M = Cu, Fe or Mo). The catalytic activity towards the ethanol reactions will be investigated through steam reforming experiments (RVE) in a fixed bed reactor, following the main products formed by on line liquid and gas chromatography and mass spectrometry measurements, as well as characterizing the extent of carbon deposition on the catalysts by ex situ scanning and transmission electron microscopy and energy dispersive x-ray spectroscopy at the end of the experiments. The most promising catalysts will electrochemically studied by polarization curves and ac impedance measurements, in a SOFC unit cell test fixture directly fed with ethanol, after which the possible formation of carbon in the anode will be monitored.
