NOVELTY - Starting fuel processor comprises generating heat using electrical heater, supplying fuel source to the burner, catalytically generating heat in the burner to heat the reformer, applying the fuel source to the reformer, and generating hydrogen in reformer. The fuel processor comprises reformer and burner. The burner provides heat to the reformer. The heater heats the burner or fuel source provided to the burner.    USE - For starting fuel processor used in fuel cell systems.    ADVANTAGE - The invention improves fuel cell system efficiency.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) fuel cell system for producing electrical energy comprising fuel processor including reformer and burner, control logic configured to regulate heat transfer or temperature for component(s) within the fuel cell system, and fuel cell including fuel cell stack to produce electrical energy using hydrogen output by the fuel processor. The fuel cell includes heat transfer appendage that includes portion arranged external to the fuel cell stack and is in conductive thermal connection with internal portion of the fuel cell stack. The fuel source heating system for heating fuel source before catalytic heat generation in burner in fuel processor comprising reformer receiving the fuel source, burner configured to provide heat to the reformer, and electric heater configured to heat the burner or the fuel source to the burner. The reformer is configured to output hydrogen and includes catalyst facilitating the production of hydrogen; and    (2) shutting down a fuel cell system comprising stopping electrical energy generation in the fuel cell, discontinuing supply of fuel source to the reformer configured to receive the fuel source and output hydrogen, generating heat in the burner to heat to the reformer after discontinuing the supply f the fuel source to the reformer, discontinuing heat generation in the burner, and flushing the burner with air. The fuel cell system comprises fuel cell receiving hydrogen from fuel processor. The fuel processor includes reformer and burner heating the reformer.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic operation for fuel cell system.
