Abstract

A sintered fuel cell electrode or filter having a layer of fine pores and a layer of coarse pores of controlled porosity is formed by adding powdered carbon of the required fine particle size into a ring with a lip of the required depth of the layer, placing a second ring over the first assembly and adding powder of the required coarse particle size to this ring to form the second layer, compacting the two powder layers together and then sintering. The powder may be compacted at 500-8,000 p.s.i. either by pressure or by vibration and sintering is effected at 1200-2400 DEG F. in an atmosphere of 90% argon-10% hydrogen.ALSO:A sintered fuel cell electrode or a filter having a layer of fine pores and a layer of coarse pores of controlled porosity is formed by adding powder of the required fine particle size into a ring with a lip of the required depth of the layer, placing a second ring over the first assembly and adding powder of the required coarse particle size to this ring to form the second layer, compacting the two powder layers together and then sintering. The preferred powder is Ni metal powder but metals of Group VIII and Ib of the Periodic Table and also carbon may be used. The powders are compacted at 500-8000 p.s.i. either by pressure or by vibration and sintering is effected at 1200-2400 DEG F. in an atmosphere of 90% argon-10% hydrogen. The metal powders are selected with a particular mean particle size and size range which depends on the required pore size of the sintered product. Many different examples are given of particle sizes and the final porosities of the sintered product.
