Research abstract
In Phase I, Mainstream Engineering demonstrated that a high concentration liquid-fed fuel cell system would significantly exceed the energy density of existing military batteries. In this proposal, we describe our Low Temperature Extended Lifetime Fuel Cell (LoTEL-FC) hybrid power system for unattended ground sensors. The system operates over a temperature range of -25°C to 65°C (13°F to 149°F) using an undiluted fuel source. In comparison to the existing unattended ground sensor primary battery-based power system, the LoTEL-FC system lasts twice as long, is smaller, and weighs half as much. Additionally, the LoTEL-FC system has a payback period of only 15 months. In Phase II, we will develop and test three progressively more complex LoTEL-FC systems and conclude Phase II at TRL 7.
