International Classification:

H01M 806

US Classification:

429 20, 429 19, 429 34

Abstract:

A fuel processor and integrated fuel cell including a monolithic three-dimensional multilayer ceramic carrier structure defining a fuel reformer and including an integrated fuel cell stack. The reformer includes a vaporization zone, a reaction zone including a catalyst, and an integrated heater. The integrated heater is thermally coupled to the reaction zone. The fuel processor further includes an inlet channel for liquid fuel and an outlet channel for hydrogen enriched gas. The fuel processor is formed utilizing multi-layer ceramic technology in which thin ceramic layers are assembled then sintered to provide miniature dimensions in which the encapsulated catalyst converts or reforms inlet fuel into a hydrogen enriched gas.

Abstract:

A hydrogen generator including a three-dimensional multilayer ceramic carrier structure defining a fuel reformer. The reformer includes a vaporization zone and a reaction zone including a catalyst. The reformer is operational as either a steam reformer, a partial oxidation reformer or an autothermal reformer. The fuel reformer, or processor, further includes an inlet channel for liquid fuel and an outlet channel for hydrogen enriched gas. The fuel processor is formed utilizing multi-layer ceramic technology in which thin ceramic layers are assembled then sintered to provide miniature dimensions in which the encapsulated catalyst converts or reforms inlet fuel into a hydrogen enriched gas.

US Classification:

422/198000, 422/211000, 422/222000, 422/110000

Abstract:

A multilayered ceramic chemical combustion heater for use in an integrated fuel reformer including a three-dimensional multilayer fired ceramic carrier structure defining at least one ceramic cavity therein and a method of forming the chemical combustion heater. A catalyst is formed in combination with the at least one cavity, being introduced into the cavity subsequent to the firing of the ceramic structure, thereby defining a closed heating zone. The catalyst provides for complete air oxidation of an input fuel. The chemical combustion heater generates heat in proportion to the feed rate of the input fuel and air. The ceramic cavity further includes a fuel inlet, an air inlet, or a combination pre-mixed fuel/air inlet, and an outlet. Feedback control of the feed rate of the input fuel and air allows for the maintenance of the chemical combustion heater at a specific temperature. The fuel processor includes a monolithic three-dimensional multilayer ceramic carrier structure defining a fuel reformer having heat provided by the integrated chemical combustion heater.

International Classification:

H01L 2120
H01L 21225

US Classification:

437127

Abstract:

A method for making a self-aligned IID structure for an LED (10) is provided. This self-aligned IID structure is accomplished by depositing a dopant layer (17) over the LED structure. A polymeric material is deposited over layer (17). The polymeric layer and dopant containing layer (17) are etched to a predetermined position. The remaining polymeric material is removed from the LED (10) structure. The LED (10) structure is annealed to produce an IID structure by laterally diffusing dopants from layer (17) into at least one side wall of the LED (10).
