Role of membranes and membrane reactors in the hydrogen supply of fuel cells

Production, storage and supply of high-purity hydrogen as a clean and effic ient fuel is a key point for the development of fuel cell technology, in pa rticular in vehicle traction. Presently, technologies for handling liquefie d or gaseous hydrogen in transports arc not available so that various alter native fuels are considered with the aim of in-situ generation of hydrogen through catalytic processes. The concept of integrated membrane reactors (M Rs) can greatly benefit to these technologies. Particular emphasis is put o n inorganic membranes and their role in MR performance for H-2 production.
