Abstract
Composite metal membranes are disclosed that contain an intermetallic diffusion barrier separating a hydrogen-permeable base metal and a hydrogen-permeable coating metal. The barrier is a thermally stable inorganic proton conductor.
Claims15
A nonporous composite metal membrane comprising a hydrogen-permeable base metal and a hydrogen-permeable coating metal characterized in that said base metal and said coating metal are separated by a barrier which prevents intermetallic diffusion between said base metal and said coating metal at a temperature of at least 500.degree. C., said barrier comprising an inorganic proton conductor other than pure metal or a pure metal alloy.
