ABSTRACT:
The reaction of alkali, alkali-earth metal hydride with water is utilized for the generation of hydrogen in a novel generator configuration. This overcomes the problems encountered in earlier hydride based generator configurations inasmuch as it overcomes the problem associated with the expansion of the hydride upon its conversion to hydroxide or oxide when reacting with water. This is accomplished by using a hydride cartridge of unique configuration. The combination of the corrugated cartridge structure and the wicking material dispersed throughout the cartridge facilitate the complete utilization of the hydride and water in a demand responsive mode. This is important in applications where intermediate hydrogen storage is impractical, as is the case in the use of these generators--e.g., for electric power generation in fuel cells in general and for Underwater Vehicles specifically because space restraints.
