Abstract
A number of embodiments of reformers for reforming fuel for a fuel cell that includes an elongated catalyst bed with fuel to be reformed being delivered at one end of the bed and extracted from the other end of the bed. Heat is applied to a greater extent at the inlet end of the catalyst bed than the outlet end to prevent the formation of carbon monoxide in the products delivered from the outlet. In all embodiments, the catalyst bed has a spiral configuration and the fuel is heated before it is delivered to the catalyst bed. In some embodiments the same heat sources are employed for heating both the fuel and the catalyst bed.
