| The present invention relates to porous articles, including porous ceramic materials, which can be used in a variety of settings, but find particular use in connection with electrochemical devices such as fuel cells, as well as methods of their manufacture and use. The porous ceramic may have, in some aspects of the invention, an average pore size of between about 1 micrometer and about 300 micrometers, and in some cases, certain advantageous permeability characteristics with respect to species useful in certain types of electrochemical devices. In some cases, the ceramic may be sufficiently porous to allow gaseous molecules (e.g., air or oxygen, gaseous fuels, etc.) and/or liquids (e.g., water or liquid fuels) to be transported therethrough, and/or the ceramic may be substantially resistive or impermeable to a liquid such as a non-wetting liquid, for instance, a liquid metal such as liquid (molten) tin. Another aspect of the invention is generally directed to systems and methods of forming such porous ceramics. In one set of embodiments, a porous ceramic may be formed by impregnating a template (for example, an interconnected template, typically three-dimensional) with a ceramic precursor, causing the ceramic precursor to form a ceramic having an open channel structure, and removing the template. The ceramics of the present invention may find use in a wide variety of applications, including kiln furniture, filters, catalyst supports, fuel cells, carriers for absorbents, insulators, or separators (e.g., for a burner and a flame), and the ceramics may be useful at a broad range of temperatures. For example, a ceramic may be used to separate a fuel from an electrode in a fuel cell (for instance, by converting fuel molecules to produce reaction products), as the ceramic may be permeable to a gas and/or a liquid. Other aspects of the invention relate to kits involving such ceramics, methods of promoting the making or use of such ceramics, and the like. | ||||||

| Methods of treating a carbon foam precursor to facilitate subsequent foaming of the material at low pressures, which may be on the order of about 0.5 to 1.5 atmospheres, are disclosed. In one embodiment, the carbon foam precursor is subjected to partial devolatilization under controlled conditions with subsequent foaming being effected at low pressure. The carbon foam precursor may be one of various forms of coal including raw coal, coal extract mesophase pitch, synthetic mesophase pitch or petroleum based pitch.

In another embodiment, the precursor after being converted into a powder is subjected to oxidation prior to foaming. In another embodiment of the invention a high density carbonaceous material is produced by oxidizing a carbonaceous feedstock to remove from the feedstock volatile gases followed by solvent treatment to remove hydrocarbons thereby providing a carbonaceous feedstock which when coked will produce a material of higher density. | ||||||

| 169 | Method and Apparatus for Producing a Carbon Based Foam Article Having a Desired Thermal-Conductivity Gradient | US11862325 | 2007-09-27 | US20090087373A1 | 2009-04-02 | James W. Klett; Christopher Stan Cameron |
| A carbon based foam article is made by heating the surface of a carbon foam block to a temperature above its graphitizing temperature, which is the temperature sufficient to graphitize the carbon foam. In one embodiment, the surface is heated with infrared pulses until heat is transferred from the surface into the core of the foam article such that the graphitizing temperature penetrates into the core to a desired depth below the surface. The graphitizing temperature is maintained for a time sufficient to substantially entirely graphitize the portion of the foam article from the surface to the desired depth below the surface. Thus, the foam article is an integral monolithic material that has a desired conductivity gradient with a relatively high thermal conductivity in the portion of the core that was graphitized and a relatively low thermal conductivity in the remaining portion of the foam article. | ||||||
