Acting as a mini-CHP plant, a fuel cell heating device can generate electricity and heat for single-family homes with high efficiency. Until now, it has been mainly economic reasons that have hampered the widespread market introduction of this technology. The BINE Projektinfo brochure entitled "Fuel cell generates electricity and heat for homes" (10/2016) presents a new device with a solid oxide fuel cell (SOFC) that has been developed to series production level. The developers have managed to reduce the manufacturing and installation costs and also improve the durability of the components.
Mini-CHP plant provides electricity and heat for single-family homes
The device provides an electrical output of 0.7 kW and a thermal output of 1.3 kW. A standard gas condensing unit is integrated to cover peak heating demands.
The overall efficiency is over 90%. All components are compactly arranged in a casing.
The negative pressure prevailing within the casing provides an effective safety concept to counter the risk of undetected gas leaks.
Previous devices were mostly based on overpressure. With the new unit, the developers have succeeded in halving the production and installation costs compared with previous systems.
The fuel cell heating device was tested in practice as part of the Callux energy research field trials, which involved devices from different manufacturers.
Fuel cells can be operated with natural gas or with hydrogen and methane generated from renewable energies or biomass.
The new fuel cell heating unit has been developed by Vaillant GmbH in collaboration with partners from research and industry.

MPQ scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.
Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor...
Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while...
Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
