CIDETEC is working on a project the aim of which is to carry out a direct assessment of the technology of fuel cells for “mini” applications which have between 1 and 10 watt power requirements – such as for mobile phone or PDA chargers or for remote signalling, etc. to this end, a series of technologies are being developed in order to obtain a house technology mini fuel cells, including the design and enhancement of EMAs (electrode-membrane assemblies), of structural elements (current collectors, shutting-off devices) and of the electronics for current enhancement (including the use of supercondensers for the supply of current peaks).
This work is currently following two lines of investigation, depending on which fuel is used. The first, using hydrogen mini fuel cells (stored in a small metal hydride cartridge), while the current focus is on the use of direct methanol (DMFC). To date it has been possible to assemble and test a 1.5W hydrogen mini fuel cell prototype which, combined with supercondensers, has been able to power a mobile phone enabling calls to be made and received.
Apart from the use of methanol as a fuel, other lines of investigation currently under way are the perfecting of a design of a new mini fuel cell the protection of which through taking out a patent is being processed; the use of new thin-layer EMAs which will provide greater yields with a significant reduction in the use of noble metals as electrocatalysts and, thus, reduce the cost of the cell.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
