A program for the development of a hydrogen generator for use with pem fuel cells in uuv applications is proposed. hydrogen is generated by reacting alkali and alkaliearth metal hydrides with water. pure hydrogen and alkali-alkali earth metal oxides or hydroxides are formed. energy densities may… More

This project offers a solution to the problem of providing electrical power at remote locations in polar environments. a proton exchange membrane fuel cell operating on stored hydrogen and ambient air can operate unattended for six months or more. the effort includes the design, fabrication, and… More

The object is the development of a miniature hydrogen generator for small proton exchange membrane (pem) fuel cells. energy density of this rechargeable power source is 6 to 8 times higher than that of rechargeable batteries. the hydrogen generator is the key for utilizing the long life pem fuel… More

The proton exchange membrane (PEM) fuel cell is being considered as power source for a variety of applications (1-4). Gravimetric and volumetric energy density, life cycle costs, ease and safety of operation are major considerations which may favor a PEM fuel cell power source over batteries. The… More

It is the purpose of this work to investigate all feasible hydrogen-based fuel cell forms capable of being used in military applications. Current support equipment found on naval and marine ships are being powered by diesel generators or batteries. These power sources are plagued with noise, … More
