Development of a PEM fuel cell powered portable field generator for the dismounted soldier

The increasing use of electronic technologies by the dismounted soldier is placing a growing burden on the power sources required to operate them. Battery technology, which is close to the limit of development cannot provide for the soldiers power needs at an acceptable weight. Air breathing proton exchange membrane (PEM) fuel cells in combination with advanced hydrogen generation technologies, are suggested as a viable alternative, providing greatly increased energy densities. An application as a portable field generator is suggested, with the fuel cell system acting as a charger coupled to rechargeable batteries.
