A Boost of Energy for Service Robots 350 Watt Fuel Cell System for grid-independent electricity supply

16.04.2007
Mobile service robots are a future-oriented market product. Autonomous vacuum robots are already commercially available on the market. Service robots are finding their place, not only as household devices or lawn mowers, but also in medical and security fields.

An important prerequisite for their continued market penetration is finding innovative solutions to meet the high energy consumption. Together with the Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS, the Fraunhofer for Solar Energy Systems ISE developed an electrical power supply for robots, which is based on fuel cells. These and other developments from the business area "Hydrogen Technology" at Fraunhofer ISE are being presented at the Hanover Trade Fair from 16-20 April.

Powerful portable electricity supply systems in the range of several hundred watts are essential for the development of service robots. Today, rechargeable battery technologies cannot meet the energy demand of such applications in a satisfying way. Two Fraunhofer Institutes present a new solution: Fraunhofer ISE developed a hydrogen-based 350 Wel fuel cell for a robot platform which was designed by Fraunhofer IAIS. Achieving an energy efficient operation as well as an optimized thermal management were the main factors here.

Grid-independent electricity supplies with long operating times are not only required for the field of service robotics, but also for telecommunication systems, signal systems, measurement stations as well as small electric vehicles. Fraunhofer ISE develops compact and automated fuel cell systems with a nominal power range between10 Wel and ca. 500 Wel. The researchers in Freiburg focus on membrane fuel cells for operation with hydrogen, reformate gas, chemical hydrides, methanol or ethanol. The stack concept, developed at Fraunhofer ISE, ensures reliable operation even for long lifetimes. The system technology permits a flexible integration for a variety of different applications.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
