IMPROVEMENTS IN AND RELATING TO GAS GENERATORS

摘要

The invention provides a gas generator comprising an assembly (1) comprising a layer (5) of a first material, the first material separating a first space (9) from a second space (11), and means for provided a differential across the layer for at least one species, the layer (5, 13) being capable of transporting electrons and transporting ions of the at least one species and resisting the flow of gas from one space to the other. It is particularly preferred that urania doped with one or more rare earth metals contribute to the first material layer. Improved efficiency and flow rates of gas generation result.
