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: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
