POROUS NI SUPPORTS FOR THIN FILM MEMBRANES

Loránd BÜKKÖSI, Ioan VIDA-SIMITI

Abstract


Metal-supported solid oxide fuel cells (SOFCs) are promising due to their good mechanical and thermal properties. Stainless steels are often used as a supporting metal. In this study, the possible use of Ni as a supporting metal was tested. Spherical (purity 99.8 % of nickel), 5 to 15 μm particles and irregular (purity 99.99 % of nickel), particle size under 6 μm, of Ni powders were used. Porous nickel supports were successfully made by uniaxial pressing of nickel powders at 400 MPa of pressure, sintering was done in vacuum, 10-5 Torr at 550 oC. The sintering time was 60 minutes in order to obtain a high open porosity. Sintered samples were characterized by electron microscopy and mercury porosimetry.  

Key words:  Ni powder, porous supports, hydrogen separation membranes
