Embodiment Construction

[0014] Exemplary embodiments of the present invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. Of course, it should be understood that in the development of any such practical implementation, many device-specific decisions must be made to achieve the developer's specific goals, as consistent with system-related and business-related constraints that can be derived from a device to another device may differ from each other. Moreover, it is to be understood that such a development effort, possibly complex and time consuming, would be the route taken by those skilled in the art having the benefit of this disclosure.

[0015] figure 1 is a block diagram of the pre-reformer A integrated with the fuel reformer B used in supplying the hydrogen-rich reformate to the fuel cell stack D as fuel. figure 1 is highly simplified and is intended to illustrate the manner in which these systems may be co...

Abstract

Apparatus and methods for rapidly heating one or more reactants for a fuel reformer. The device comprises: a combustion section having an outer wall enclosing a combustion chamber and a catalyst disposed within the combustion chamber; a heat recovery section in fluid communication with the combustion section and having an outer wall defining a heat recovery chamber; at least one heat exchange element located within the heat recovery chamber, the said heat exchange element having an inlet for receiving reactants and an outlet for directing heated reactants out of the heat recovery section; raising the combustion section relative to the heat recovery section so that heated combustion gases are displaced downwardly into the heat recovery section; wherein The inner diameter of the housing is less than about 10 inches, or the housing has a length to diameter ratio of about 7:1 to about 4:1.

Description

Background technique [0001] Fuel cells generate electricity through chemical redox reactions and offer significant advantages in cleanliness and efficiency over other forms of power generation. Typically, fuel cells use hydrogen as the fuel and oxygen as the oxidant. The generation of electricity is generally proportional to the rate at which the reactants are consumed. [0002] A significant drawback inhibiting the wider use of fuel cells is the lack of a broad hydrogen infrastructure. Hydrogen has relatively low volumetric efficiency and is more difficult to store and transport than the hydrocarbon fuels commonly used in most common power generation systems. One way to overcome this challenge is to use a reformer, which converts the hydrocarbons into a hydrogen-rich gas stream that can be stored or used nearby as a fuel cell feedstock. [0003] Hydrocarbon-based fuels such as natural gas, LPG, gasoline and diesel require conversion processes for use as fuel sources for mo...
