Накратко на български

Микротръби от метални оксиди се използват за създаване на миниатюрни горивни клетки. Тези устройства помагат за повишаване на ефективността при превръщането на енергията, което намалява замърсяването на околната среда и щади природните ресурси.

Microtubular solid oxide fuel cells Finally In MicroScale

Reducing losses in energy conversion is one of the most challenging tasks of the society, as to this day, most fuels are burned in combustion engines with low efficiency. Increasing energy conversion efficiency has direct positive impact on lowering environmental pollution and contributing to sustainable use of natural resources – both immensely important problems in modern day society. Resource efficiency and reduced burden on environment have also been identified as critical components of future EU economy (e.g. The European Green Deal). Fuel cells hold great promise for the long waited revolution in efficient energy conversion. Although efficient solid oxide fuel cells (SOFCs) are available, their widespread dissemination into portable devices is severely hindered by lack of durability, slow start up times and high cost. To overcome these problems, tubular instead of planar systems are proposed. The disadvantage of macroscale tubular configurations is their low power output per volume. However, tubular geometries are principally easier to miniaturize and provide use convenience not available on planar fuel cell systems. This project aims to demonstrate SOFC based on smallest microtubes made of metal oxide materials (yttria stabilized zirconia – YSZ). Material precursors developed by researchers at the Institute of Physics, University of Tartu are optimized for making uniform metal oxide microtubes with approximately 100 micron diameter and 10 micron wall thickness. These optical quality microtubes are characterized to reveal their mechanical and electrochemical properties. Covered with suitable electrode materials, fuel cell element based on single microtube and multiple microtubes (a fuel cell stack) are constructed and tested to validate in the laboratory the technology that would allow to build the world’s smallest solid oxide fuel cell.

Цел на проекта

A breakthrough in economically viable efficient energy conversion has been long waited, with fuel cell technology being a promising candidate. Recently, tubular Solid Oxide Fuel Cells (SOFCs) have received increased attention due to possibility to shorten start-up times, reduce material losses and lower costs of fuel cells. In order to reach sufficient volumetric power density, decrease working temperature and reduce costs, the diameter of the SOFC tubes has to be reduced at least an order of magnitude, compared to state of the art (at or above 1 mm). In the recent years, the hosting group of the project has demonstrated fabrication of yttria-stabilized zirconia (YSZ) microtubes with diameters <100 µm and tested their viability for use as an electrolyte in microtubular SOFCs. The FIMS project is focused on innovative development of controllable YSZ microtube fabrication methods and subsequent use of the microtubes in construction of a SOFC stack to prove commercial potential. A method for fabrication of optical quality fluorescent microtubes with controlled dimensions (diameter <100 µm, wall thickness 5-10 µm) and facile structural defect detection with optical techniques will be realized. Porous electrode deposition on the microtubes will be refined and a microtubular electrolyte supported pilot SOFC stack will be constructed and characterized. The target of FIMS is to promote transfer of knowledge through training and career development of the Fellow in the multidisciplinary field of SOFC technology, in order to re-enforce professional maturity and independence of the Fellow. Two secondments – academic and industrial – further improve the training and collaboration network of a young scientist. The project will have positive impact on the Fellow's career progress towards becoming a leading researcher, and supports enhancement of environmental protection and sustainable resource use.
