The fuel cell manufacturer Sunfire Fuel Cells GmbH (formerly known as New Enerday GmbH) and the electronics manufacturer PRUFREX will be working in partnership in the development of SOFC systems (solid oxide fuel cells) for the new "Sunfire Home" and "Sunfire Remote" range of products.

Sunfire Fuel Cells produces systems for generating environmentally friendly, independent and cost-efficient energy, and related supply solutions. These micro combined heat-and-power units are put to use in residential buildings and for supplying electricity for off-grid applications. PRUFREX, an electronics manufacturer based in Cadolzburg, close to Nuremburg, germany, is an expert in control intelligence for e-motors, burners and other electronically controlled applications. PRUFREX provide mission critical sulutions for key points of device operation.

With its ignition spark generator with integrated flame monitoring (ZFG), PRUFREX offers Sunfire an all-in-one solution for the entire device. This means that ignition of the supply of natural or liquefied gas along with the  monitoring of reliable ignition through measurement of the ion current are combined in one unit and occur in parallel. The ignition spark generator is put to use in the "Sunfire Home 750", fuel-cell-based power supply/heater for single-family homes, as well as "Sunfire Remote", the stationary power supply for off-grid applications, such as the oil and gas insutries, or applications for surveillance and telecommunications.
