Abstract

A method of forming thin porous sheets of ceramic material for use as electrodes or other components in a molten carbonate fuel cell is disclosed. The method involves spray drying a slurry of fine ceramic particles in liquid carrier to produce generally spherical agglomerates of high porosity and a rough surface texture. The ceramic particles may include the electrode catalyst and the agglomerates can be calcined to improve mechanical strength. After slurrying with suitable volatile material and binder tape casting is used to form sheets that are sufficiently strong for further processing and handling in the assembly of a high temperature fuel cell.

Method of preparing thin porous sheets of ceramic material

Patent Swarr, T E ; Nickols, R C ; Krasij, M

A method is described of forming a thin porous sheet of ceramic material comprising: providing a slurry of fine ceramic particles and liquid carrier including binder material; spray drying the slurry to form generally spherical porous agglomerates having a rough surface texture; calcining the agglomerates at a sufficient temperature to drive off the binder material and fix the fine ceramic particles in agglomerates of spiky morphology while substantially maintaining the porosity of the particles; slurrying the calcined agglomerates with binder and volatile material to form a slip for casting as a tape; spreading a thin layer of the slip ontomore »« less
Porous electrode preparation method

Patent Arons, Richard M ; Dusek, Joseph T

A porous sintered plaque is provided with a bimodal porosity that is especially well suited for use as an electrode within a molten carbonate fuel cell. The coarse porosity is sufficient for admitting gases into contact with the reaction surfaces while the fine porosity is wetted with and retains molten electrolyte on the reaction sites. The electrode structure is prepared by providing a very fine powder of such as nickel oxide and blending the powder with a suitable decomposable binder to form a solid mass. The mass is comminuted into agglomerate size particles substantially larger than the fine oxide particlesmore »« less
