The EFOY Hydrogen 2.5 Fuel Cell supplements the comprehensive product range of SFC Energy with energy solutions in the higher power range and provides reliable, powerful and uninterrupted climate-neutral energy. Power output from 2.5 to 50 kW can be individually scaled. The operation and installation are very simple and no emissions are generated. That is why the EFOY Hydrogen Fuel Cell can also be used in environmentally sensitive areas and is very quiet and efficient. The EFOY Hydrogen 2.5 is used, for example, to supply power to mobile communications infrastructure, smart traffic applications or to provide emergency power to critical infrastructure.

Annual CO2 savings
Compared to a conventional diesel generator, for example, a 5 kW hydrogen fuel cell energy solution saves up to 45.6 tons of CO2 based on an assumed annual demand of 43,800 kilowatt hours (kWh). This corresponds to the driving perfomance of a diesel-powered car of about 250,000 kilometers.
Critical infrastructures depend on a reliable power supply. A reliable emergency power system is of critical importance especially when using modern information and communication technology, such as with for authorities and organisations with security tasks (emergency services). An effective, broadband communication between the scene and situation centres is necessary for an optimised and realistic assessment of the situation. Conventional battery solutions make it very difficult to ensure long operational reliability for several days.
EFOY Hydrogen Fuel Cells are already in use in many locations to provide backup power. The fuel cell modules switch on completely automatically and take over the load no later than 20 seconds after the power fails. Compared to solutions with diesel generators, no CO₂ emissions are generated here. Another advantage of the EFOY Hydrogen Fuel Cell is the low maintenance effort as well as the low ageing tendency in standby mode. This ensures system availability for long periods of time.
EFOY H2Cabinets serve as a customized overall solution for numerous applications. In particular, they are used as backup power supply systems for emergency power supply. Several EFOY Hydrogen fuel cell modules can be combined in the cabinet. The EFOY Hydrogen Cabinet is available in two versions – outdoor and indoor.
The H₂Genset is a flexible and mobile generator using hydrogen for use in areas without access to the conventional power grid, e.g. on construction sites, at outdoor events, for the temporary power supply of telecommunication masts or as a mobile emergency power supply in the event of catastrophes.
Fuel for the EFOY Hydrogen 2.5
Hydrogen is gaseous, colourless and odourless. It is typically stored in compressed gas cylinders from 200 to 300 bar. Hydrogen – based on its weight – has a very high energy density. The fuel is harmless to the environment and non-toxic to humans.

1) With increasing operating hours and temperatures >30 °C, the output power gradually decreases. 2) The leakage rate increases proportionally with increasing operating hours of the fuel cell module. 3) When installed in a suitable cabinet with integrated heating. Otherwise, a base load of 1,000 W is required. 4) Higher altitudes may result in a reduction in power.
