Abstract

This work is devoted to identify operating conditions to maximize the life of power supply, meet the required power output and improve fuel consumption efficiency. We devise a framework for designing fuel cell power supplies for field sensor networks, which have important applications in environmental monitoring, wildlife preservation, in disaster monitoring and in border security. The high efficiency, low emission and zero noise pollution features of fuel cells have made them a promising clean power source. Especially, proton exchange membrane fuel cells are promising alternative to conventional fossil fuel system, because they are clean, quiet and operate high efficiencies. However, challenges remain in achieving long lives due to shortage factors such as degradation and hydrogen storage. These shortages mainly depend on the operating conditions of PEM FC, load, start/stop cycles, working temperature, humidity etc.
