Energy Cell
Ensuring a year-round autonomous energy supply involving photovoltaics was previously only possible by having environmentally-damaging diesel generators to fall back on. Fronius has found a new solution - the Fronius Energy Cell. In future, the energy cell can be used to convert excess energy into hydrogen for storage, converting it back into useful power when needed.
Please note that the Fronius Energy Cell is not yet certified according to UL.
The stationary Fronius Energy Cell
The Fronius Energy Cell comprises an entire system of regenerative energy creation and storage. The final version will fulfil two roles - performing electrolysis and the function of the fuel cell.
A PV system (1) converts sunlight into direct current, which is then either converted into alternating current by an inverter (4) and channelled to the consumers (red arrow), or (should any power not be needed straight away) used to decompose water into oxygen and hydrogen = electrolysis function of the Energy Cell (2). The hydrogen is then stored in a hydrogen tank (3). Stored hydrogen is converted back into electricity (2) using the fuel cell function of the Energy Cell when it is needed, i.e. when no power is being generated by the solar modules. Clean, emission-free energy is now available for use at all times (blue arrow).
The fuel cell function (hydrogen into electricity) of the Fronius Energy Cell is already ready for mass production. In the next version of the Fronius Energy Cell the electrolysis function will also be fully integrated.

The use of the Fronius Energy Cell in mobile applications
The fuel cell part of the Fronius Energy Cell can also be used in mobile applications. Examples of some successful portable Fronius Energy Cell projects can be found below.
