Dr Alberto Bollero Dr Gorka Salas [\/et_pb_text][et_pb_text _builder_version=”4.9.4″ _module_preset=”default” custom_margin=”27px||29px|||”]<\/p>\n Solid oxide fuel cells (SOFCs) are one of the most promising renewable energy devices and green technologies [1]. This next-generation power system makes possible achieving high-energy conversion efficiencies using alternative fuels (e.g. hydrogen, natural gas, biogas and solid carbon) accompanied by a minimum carbon dioxide production and no pollutant product. Reduction of the operating temperature in SOFCs will allow their commercialisation as portable power source and will open the path to their integration in electric vehicles.<\/p>\n 3D-SOLCELL<\/em> aims at the fabrication of a new generation of green 3D-printed SOFCs with enhanced efficiency through optimized geometries, by combining two advanced manufacturing techniques: inkjet for the fabrication of the cathode (lanthanum strontium ferrite) and Fused Filament Fabrication (FFF) for the fabrication of the anode (Ni\/YSZ), making use of IMDEA\u2019s knowledge on the chemical synthesis of composites with a high-load particle content (> 80wt.%) [2].<\/p>\n The precursor for fabrication of the cathode will be ferrite powder obtained through a green (chemicals-free) recycling procedure developed by IMDEA Nanociencia [3], followed by compositional adjustment by addition of the corresponding metal salt or precursor. Alternatively, lanthanum strontium ferrite nanoparticles will be prepared by bottom-up approaches for comparison. The anode material will be synthesized by ball milling of the elemental constituents. Performance of SOFCs is influenced by morphology, microstructure and particles distribution in the electrodes. Optimization of these material parameters will be possible by application of the self-developed \u201cflash-milling\u201d method, providing a homogeneous submicrometer particle size in record milling times (< 5 min) [3,4].<\/p>\n \u00a0 \u00a0[1] R.M.

Research and technological development should be oriented to produce novel solid oxide fuel cells, and the fabrication of prototypes to demonstrate their functionality.<\/p>\n The researcher will have the opportunity of working in a multidisciplinary scientific environment at IMDEA Nanociencia (Severo Ochoa Center of Excellence) and in the framework of international projects. A close collaboration with the groups leaded by Dr G. Salas and Dr A. Bollero will make possible the combination of expertise on the synthesis of functional nanoparticles and composites, design of materials with tuneable properties, advanced and sustainable fabrication techniques and construction of prototypes. This fruitful combination of expertise will ease the creation of a new research line at IMDEA Nanociencia with objectives well aligned with the strategic goals of the centre and with the EU technological and environmental priorities. <\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.9.4″ _module_preset=”default”]<\/p>\n The following secondments are considered:<\/p>\n
