SFC Energy AG, a leading international supplier of stationary and mobile hybrid fuel cell solutions, has been awarded a contract by FKS GmbH for the provision of EFOY ProCube fuel cell systems to secure the back-up power supply of the BOS digital radio system of the District Administration of Meissen, Saxony.

The district administration office of Meissen uses the BOS radio system for the digital alerting of the fire department, rescue services and disaster management in emergency and crisis situations. All radio stations are connected to the public 230 V power grid. The commissioned back-up solution with EFOY ProCube must be capable of maintaining the radio system in uninterrupted operation for at least 72 hours even in the event of a power failure. The current EFOY solution has a 60 Ah battery capacity. This allows the digital alarm converter to operate for approximately 46 hours without recharging by the fuel cell. The EFOY Pro fuel cell’s switch-on threshold is programmed accordingly low; it switches on fully automatically and recharges the battery. With 2.5 l of fuel from the EFOY fuel cartridge, the system can recharge about 2.7 kWh. This allows the batteries to be fully charged three times and enables the system to operate autonomously for at least five more days. This far exceeds the technical requirements. In the event of a power failure, this results in an operating time of at least 7 days.

FKS GmbH is a specialist for the configuration, installation and maintenance of radio and communication technology devices and systems. In the field of switching and communication technology, the company works closely with the command centres of fire brigades, rescue services and disaster management. FKS GmbH is installing the complete back-up power supply for the BOS radio system for the district administration office in Meissen. The weatherproof fuel cell solution can be easily transported and put into operation in a very short timeframe. It is used either as the sole power source or in hybrid operation with other types of power sources.

The “Back-up power supply for the BOS radio system” project is funded by the Federal Ministry of Transport and Digital Infrastructure within the framework of the National Innovation Programme Hydrogen and Fuel Cell Technology with funds totalling close to €30,000. The funding guideline is coordinated by NOW GmbH and implemented by the project administrator Projektträger Jülich (PtJ).
