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.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
