For industrial and production facilities, health care centres, transport, telecommunications, and IT sector which need an
uninterruptible power supply system that generates electrical energy, we offer an emergency power supply system PULSTAR based on ecological fuel cells. Unlike competing conventional solutions with classic batteries having detrimental effect on the environment during production, exploitation, and utilisation, we offer ready-made power supply systems with
fuel cell working on electrical grid and long-lasting individual receivers, ensuring the continuity of power supply in the event
of an outage without any problems during exploitation.
The PULSTAR backup power system is based on an ecological energy source – fuel cells. By delivering hydrogen and air, we receive electric energy and clean water as a by-product. The cell functions silently and is very small in comparison to an aggregator/battery. It can be installed in any chosen space. A standard large bottle with hydrogen ensures the system will operate at a power of 1kW for 8 hours. The fuel cells directly convert energy contained in chemical reactions into direct current energy. This transformation is highly efficient and makes a very minor impact on the environment.
The PULSTAR power supply system has been implemented and is in use of 4 clients – the Gdańsk University of Technology, the Łódź University of Technology, the Warsaw University of Technology and the Silesian University of Technology. The delivered power supply systems are composed of the following elements: a fuel cell with a power of 1.2 kW, a DC/DC converter
stabilising the tension from the cell, an inverter allowing for powering the system with alternating current receivers, and also cooperation of the system with a low-voltage distribution network. The system is equipped with a monitoring system that allows it to be controlled remotely and meters all of the system’s operating parameters. PULSTAR systems offered to research
and development enterprises are used for conducting research on both the fuel cells themselves and the system in its entirety. In addition, delivered technology enhances the didactic programme with the newest technologies in the area of electrical energy production. PULSTAR guaranteed power supply systems have been implemented in their entirety by clients. The first implementation took place already in 2003.
Advantages of the technology:
- An innovative, ecological power source based on PEM-type fuel cell.
- Failure-proof system thanks to monitoring of the fuel cell’s functioning,
registering of the feeder’s functioning and raising the alarm in case of an
outage using the Automatic Management System (SAN 3) to control the
functioning of the feeder.
- Safety is ensured by the use of redundant hydrogen anti-leaking safeguards
and power surge protection, short circuit safeguards, etc. with the RS-232
- Modular construction.
- High stability of voltage and output current and low pulsation of output
