Nokia Siemens wants to develop a solution for power blackouts affecting mobile networks base stations and are testing fuel cell backup. NSN is working with Ballard Power Systems to come up with this solution.
NTT DoCoMo of Japan is already testing the Flexi Multiradio and commercial deployment could be happening soon. Advantages this fuel cell technology poses as backup power solution over conventional batteries and diesel generators include weight and size reduction.
The base station and fuel cell combination developed by Nokia Siemens Networks with Ballard can provide 4.5 kW of power for approximately 40 hours on a single tank of fuel.
