Abstract
An oxygen generator is provided in the form of a housing having isolated first and second chambers. Oxygen-generating material is placed in the first chamber and a catalyst for activating the oxygen-generating material is placed in the second chamber. A heat-absorbing hydrated salt is also provided so as to be present during the reaction to absorb the excessive heat released upon the exothermic chemical decomposition of the oxygen-generating material. The salt has an endothermic dehydration reaction temperature below 50.degree. C. A membrane is operationally connected to the reaction chamber to allow the generated oxygen to be expelled from the reaction chamber while retaining the material contents therein.
