Fuel Cell based Uninterruptable Power Supply (UPS) an Innovative Telecommunication Application

Fuel cell products and systems are still about to break through in their markets. Among many other applications which are currently under development most success for a market entry today is seen for stationary applications where conventional batteries often operate reach their technical limits. A fuel cell system in combination with a UPS application with a power output of netto 2 kW at - 48 VDC is available now. One of the major advantages is that the back-up time is free dimensionable, simply by the installation of a long lasting hydrogen storage (e.g. compressed gas bottles) at low cost. The key funtionalities are furthermore: supply of reliable uninterruptable power for Base Transceiver Stations (BTS) in a mobile network operators telecommunication network, mid-range UPS systems for internet and other multimedia applications such as, due to free dimensionable back-up periods a more long-term power supply (for example in security demanding environments such as cable tv, fibre optical networks, backbones and more).
