A solution of ferumoxytole was fed in a glass autoclave and treated it with synthetic air. Parameters such as pressure and temperature was studied in order to achieve a desired degree of ferumoxytole oxidation, which was followed by means of UV/VIS spectroscopy.
F.07 Improvements to an existing product
COBISS.SI-ID: 5040922Thermal treatment of waste polyamide/polyurethane−polyurea copolymer was studied with the aim of assessing the potential for polyamide, caprolactam oligomers or caprolactam monomer recyclability. In view of this fact, experiments were executed in batch mode using neat nylon, neat lycra and composite fibres in nitrogen and steam atmospheres, in some of the cases adding caprolactam as a precursor for nylon depolymerisation. Evolving gas analyses were performed by FTIR spectroscopy.
F.05 Ability to launch new technological development cycle
COBISS.SI-ID: 5040666The implementation of a high-temperature PEMFC stack into a combined system with a steam methanol reformer (SMR) has been studied. Comparison of efficiency between systems with a high temperature (HT) PEMFC stack and a classical, low-temperature (LT) PEMFC stack has been made. In both systems the methanol reformer operates at 250 °C and steam-to-methanol ratio of 1.5. Classical PEMFC stack operates at 90 °C while high-temperature PEMFC stack operates at 250 °C. Additionally, the system with a classical PEMFC stack uses a catalytic burner to supply the endothermal reforming process with sufficient heat. Partial heat regeneration has been also used in this system because hot exhaust gases from the reformer need to be cooled down before entering the fuel cell stack. Modelling of both systems and sensitivity analysis was performed in Aspen Plus. The results show that efficiency of approximately 54% (based on higher heating value) can be reached with the HT PEMFC system, which is more than 40% higher efficiency compared to the LT PEMFC system
B.03 Paper at an international scientific conference
COBISS.SI-ID: 5170714Mebius d.o.o. is a young company focused on research, development, marketing and production of key components for high and low temperature PEM fuel cells. We are developing key components that represent the heart of a fuel cell : membranes, catalysts, gas-diffusion electrodes (GDE), membrane-electrode assemblies (MEA). The company is also developing its own high temperature PEM fuel cell stacks which range from a few Watts to 2 kW. Main running project of the company are (1) “VT Sklad – development of high temperature PEM fuel cell stacks” – with National Institute of Chemistry under contract for Ministry of Defense, Republic of Slovenia. Some of the completed projects show the main line of our work: (1) “HyCore – development of key components of high temperature PEM fuel cells” – with DOMEL d.d., INEA d.o.o., Jozef Stefan Institute, Financed by European Union, Ministry of Higher Education, Science and Technology of the Republic of Slovenia and Slovenian Technology Agency. (2) Feasibility study project “Energy independence” - under contract of Center for Renewable Energy Sources and Environment Safety Pivka (COVEVO).
