supplanting batteries that are so lim- ited in their storage capacity. According to Fraunhofer, a fuel-
cell powered car can fill up with the liquid hydrogen in about 3 minutes, providing a travel range of about 400 kilometers (250 miles). According to a government offi-
The Huntron Access DH Prober is designed with your test and measurement needs in mind.
Te Access DH dual head Prober lets you control variables such as dexterity, high density, tight lead spacing and speed with precise, fast and repeatable guided probing.

cial, the State of Baden-Wuerttem- berg is actively promoting expansion of the hydrogen infrastructure, thereby also supporting the nation’s automobile industry. The vision is to achieve a sustainable, future-proof mobility using sustainable energy sources —both solar and wind power. The new solar hydrogen filling sta- tion in Freiburg is viewed as a re- search platform linking renewable energy and electric mobility, using “green” hydrogen. The Freiburg fill- ing station is one of a handful of sta- tions that demonstrate what Fraun- hofer calls the entire value chain — starting from electricity generated from renewable energy, through elec- trolysis and ultimately to refueling the vehicle with hydrogen. Since its founding, Fraunhofer
ISE has been working on electrolysis technology, hydrogen for use in fuel cells and on hydrogen as electrical energy storage for renewable power sources. The hydrogen filling station serves as a reference project for re- searchers in their quest to develop emission-free mobility for the future.
Flexible Electrical Loads The electrolyzers that are used
here operate as flexible loads for the solar panels, serving to stabilize the intermittent nature of electricity from solar panels and/or wind turbines. “The transformation of our en-

Te ability to customize the Access DH probe head assemblies combined with software created using the Huntron Workstation SDK, Hardware SDK or Remote Control provides many integration and customization opportunities. Te probe head design includes pre-wired interconnections for adding built-in USB, Firewire or Ethernet instrumentation at the head.

Test Automation
As the density and complexity of circuit boards has increased, the need to accurately place a probe on a test point has grown. Huntron recognized this issue early on and released its first robotic test platform in 1991. Our Access Probers have matured over the years with increased accuracy and the ability to be customized based on your test and measurement needs.
ergy supply system to one hundred percent renewable energy is one of the challenges for our society in the coming years,” states Prof. Eicke R. Weber, director of Fraunhofer ISE. He adds: “With hydrogen, surplus electricity can be stored in any given amount and be delivered upon de- mand to the mobility sector.” The researchers at Fraunhofer
emphasize that a total conversion of our automotive system to all-electric power is essential, if we are to have sustainable mobility. And a number of European automobile manufactur- ers have climbed aboard with prom- ises to have fuel cell vehicles in vol- ume production by 2015. Even the electric and gas utilities in Germany are getting their acts together, prom- ising a hydrogen infrastructure na-

tionwide in Germany by 2017. Lead- ing oil companies and electric utili- ties there have formed the joint ini- tiative “H2 Mobility”. Principal components in the hy-
drogen fueling station in Freiburg in- clude a 30 bar pressure electrolyzer, a mechanical compressor for com- pressing hydrogen to 700 bar for storage, puffer storage at two differ- ent pressure levels, and pumps for dispensing the hydrogen. Energy is supplied by photovoltaic arrays on the filling station rooftop and on a neighboring building. The amount of energy is recorded automatically and excess power is fed to the grid through an inverter. Among the cars at the opening
was a Mercedes Benz F-CELL World Drive that has already been driven once around the world. At the open- ing day ceremony, guests were given a guided tour of the newly construct- ed Fuel Cell Test Lab located at Fraunhofer ISE.
Above the Arctic Circle In another development, H2
Logic, a Danish hydrogen fuel compa- ny, has opened a new hydrogen refu- eling station inside the Arctic Circle. While it may seem contra-intuitive to build a fueling station in this part of the world, the station will serve as a vital fuel point for many automakers testing hydrogen-powered vehicles. Car makers have begun testing their new vehicles in extreme weather to determine whether they are fit for dif- ferent climates. The station will be lo- cated at the Arctic Driving Center in Finland. H2 Logic’s new station is part of an experiment to see how fuel- ing stations work in severe climates. Some have assumed that the cold weather of the Arctic Circle would slow down fueling of vehicles. Thus far, the weather has had no effect on the speed of fueling. In fact, vehicles running on hydrogen fuel can fill up faster at the new station than any other in the world. The company has plans to build
fuel stations in other parts of the world, especially where automakers are testing new vehicles. These sta- tions will be able to serve any vehicle coming from any automaker because of the universal nozzle design of the pumps. As more hydrogen-powered vehicles make their way to the con- sumer market, H2 Logic plans to in- troduce their quick-fueling technology to more stations around the world. Contact:

assembly sections, the 2011 roadmap provides insight into the regional dif- ferences in capability between Asia, Europe and North America. Accord- ing to Marc Carter, IPC director of technology transfer, the new data sheds light on the important distinc- tion between acknowledging a tech- nology and actually having the capa- bility to employ it. Another essential addition to
the 2011 Roadmap is the link of em- ulators to industry standards and specifications. A new section discuss-
es the changes that need to occur in industry standards content to make them relevant to tomorrow’s needs. This includes the addition of a state- of-the-art level for product features that demand a higher degree of pre- cision — a level that Carter admits very few manufacturers can provide. Published as a CD, the roadmap
includes several technical resource presentations that users can access easily at their workplace. For more information or to purchase 2011 IPC International Technology Roadmap for Electronic Interconnections, visit
