Lightweight, Rugged, Portable Fuel Cell

"To operate sensors to verify future arms control agreements, inspectors will need a portable power source. The power source must be rugged, lightweight, reliable, adaptable to a variety of different sensor applications with different current/voltagerequirements, and simple to refuel in the field. We propose to develop a polymer electrolyte membrane (PEM) fuel cell that is ideal for arms control inspectors. The system is based on proven membrane/electrode assemblies. Innovative cell components andsystem design make the system rugged, reliable, lightweight, and easily transportable. A "smart" power control system enables the system to supply power at any voltage between 12 and 120 V. The system uses fuel that is easily transportable and/orobtainable nearly anywhere in the world. In Phase I we will prove the feasibility of this system by demonstrating the operation of a prototypical fuel cell stack, assessing the key design trade-offs, and producing a conceptual design for the prototypefuel cell. In Phase II we will develop the system components, complete a detailed system design, fabricate the stack, and assemble the system. Phase II will culminate with a demonstration that the system can produce 220 W of power for 12 hours. For armscontrol inspectors, the proposed system will eliminate the logistical burden of supplying power for critical sensors: it is easily transportable, provides output voltage suitable for a variety of se
