A gas generating system for generating a supply of oxygen or at least an oxygen rich gas, and a residual gas, the system including a first gas separation device for separating from a supply gas, a first gas being oxygen enriched gas, to leave a residual gas. The first oxygen enriched gas from the first gas separation device is communicated to a second gas separation device for further separating from the first oxygen enriched gas, oxygen gas. The second gas separation device generating a product gas which is at least highly oxygen enriched and a further residual gas, with at least one of the first and second gas separating devices including a ceramic membrane through which in use gas ions diffuse.
