Abstract
The present invention is a system and method of heating a reaction cell that produces hydrogen from a mixture of hydrocarbon fuel and steam. The reaction cell contains a first tube of hydrogen permeable material and a second tube of hydrogen impermeable material. The first tube and the second tube are concentrically positioned so that a gap space exists between the two tubes. A heat pipe structure is utilized to heat the gap space. The heat pipe structure defines an enclosed vapor chamber. A volume of a multi-phase material is disposed within the vapor chamber. The multi-phase material changes phase between a liquid and gas within an operating temperature range. A heating element is used to heat the vapor chamber to the operating temperature range. The vapor chamber transfers heat along its length in the same manner as a heat pipe.
