Sunfire Fuel Cells

New enerday becomes Sunfire Fuel Cells: After the takeover by Sunfire GmbH in autumn 2018, the competence centre for fuel cells in Neubrandenburg now operates under the name Sunfire Fuel Cells GmbH.

Managing directors of the cleantech company are Dr. Matthias Boltze, who has been in charge of new enerday until now, and Andreas Frömmel, who also remains Vice President Sales & Marketing at Sunfire in Dresden. Sunfire Fuel Cells is now advancing a joint platform technology for micro-CHP devices for residential buildings and off-grid power supply.

  • Sunfire GmbH from Dresden consolidates fuel cell activities in a competence centre in Neubrandenburg as Sunfire Fuel Cells GmbH
  • Managing directors are Dr. Matthias Boltze and Andreas Frömmel
  • Fuel cell technology from Sunfire, Vaillant and new enerday merges into platform technology for micro-CHP (Sunfire-Home / Sunfire-Remote)

Carl Berninghausen, CEO of Sunfire said, “With the new structure, we are consolidating Sunfire’s fuel cell activities in Neubrandenburg by creating a centre of excellence for fuel cells that is unique in Germany – both for domestic requirements and for off-grid applications.”Sunfire Fuel Cell Unit in Home

The know-how that Sunfire has acquired as a stack supplier and manufacturer of fuel cell heating devices, as well as new enerday’s experience with compact, highly integrated portable systems and the knowledge from its former partner Vaillant will be combined. Vaillant has paused its CHP activities after the development of the successful 6th generation and transferred the existing knowledge to Sunfire:

Berninghausen continued, “The combination of many years of research and development by the three German fuel cell specialists has resulted in the highly attractive solid oxide fuel cell systems that will go into series production at the end of 2019.”


With Sunfire-Home, Sunfire Fuel Cells is introducing an add-on device for supplying electricity and heat to single-family households that do not have a gas grid connection and, for example, would like to replace the existing oil heating with an environmentally friendly, efficient and innovative system. The micro-CHP solution offers a rated electrical output of 750 watts and a thermal output of 1,300 watts. In addition to reducing emissions, the advantages of Sunfire-Home include high efficiency, fully automatic operation with remote access and simple integration with modern building technology such as a peak load boiler and a hot water storage tank.
The Sunfire-Home fuel cell system can be operated both with LPG (liquid gas) and natural gas from the grid in the future. As part of the PACE market launch program, funded by the Fuel Cells and Hydrogen Joint Undertaking (FCH JU) with Horizon 2020, the first 500 devices will be placed on the market.


Looking at Sunfire-Remote, the Neubrandenburg-based company promotes compact solid oxide fuel cells (SOFC) for self-sufficient and off-grid power supply from liquid gas, which are also available for car trailers as a hybrid system with batteries and photovoltaic elements. Typical applications include the power supply of measuring and control equipment for oil and gas pipelines, the signal lighting of wind farms in the construction phase and the mobile power supply for security systems and telecommunications stations.
Sunfire-Remote has an electrical output of 400 watts and can be powered by conventional liquefied petroleum gas (LPG) in off-grid applications. When configured as a hybrid system, it also serves applications with more than 1.2 kilowatts.
