High-speed varistors
01 February, 2006Epcos has extended its CeraDiode CDS4 series with a 3 pF type that has the same solder pad dimensions (2.5 x 0.8 mm) as a TVS diode in an SOD 323 package.
Analog power supply
04 October, 2005B&K Precision has added the Model 1744 DC analog power supply to its range.
Fuel cell appliance gets field trial
20 July, 2005Ceramic Fuel Cells and Central Gippsland Institute of TAFE announce an agreement for Australia's first field trial of a fuel cell powered micro-CHP (combined heat and power) generator appliance.
Methanol fuel cell
18 October, 2004Toshiba has announced the prototype of a highly compact direct methanol fuel cell (DMFC) that can be integrated into devices as small as digital audio players and wireless headsets for mobile phones.
High temperature PEM fuel cell development
18 May, 2004A new type of polymer electrolyte membrane (PEM) is being developed by researchers at the Department of Energy’s Sandia National Laboratories to help bring the goal of a micro fuel cell closer to realisation using diverse fuels like glucose, methanol, and hydrogen.
Power cell units
28 October, 2003The PCU series of power cell units has an output of up to 900 W and made up of cells with a maximum of 12 channels. The units are suitable for prototypes as well as normal power supply needs.
Fuel cell power for portable equipment
05 August, 2003Running a laptop or other electrical equipment causes a problem when there is no access to a mains supply. If the battery runs out, where can you recharge it?
Portable power plants
09 April, 2003The Mobile Power Box has been developed at the Fraunhofer Institute for Solar energy systems ISE working in cooperation with the firm of Masterflex. It is a membrane fuel cell system supplying mains-free energy in the medium power range.
