Ultra-long duration backup for telecommunications applications using zinc/air regenerative fuel cells

For applications such as telecommunications where high availability is essential, zinc/air regenerative fuel cell technology offers a promising alternative to current methods of providing extended backup. This technology addresses the need for a cost-effective means of providing many hours of backup time in a relatively compact space, with manageable weight and zero emissions for indoor operation. This paper provides an overview of the operation and capabilities of zinc/air fuel cell technology in general and relative terms. It also discusses Metallic Power's plans to commercialize the technology in the context of telecommunications backup power applications for which it is particularly well suited.
