A compact, energy efficient steam reforming system for automotive applications has been under development at the Pacific Northwest National Laboratory. At the IMRET 5 conference, results were presented describing the operation of a thermally integrated, energy efficient, compact, microchannel steam reforming system capable of converting a liquid hydrocarbon fuel (isooctane) into a reformate stream sufficient for a PEM fuel cell with > 10 kWe capacity. Since this demonstration, the project has focused on performing testing in smaller scale steam reforming reactors to further reduce the reforming reactor volume, demonstrate fuel flexibility and address other issues. A test stand, nominally 1/20th the scale of the previous steam reforming demonstration, was constructed and smaller scale reactors have been used in testing. Significant gains have been made with respect to increasing the volumetric productivity of the reactor, suggesting that the 10 kWe reactor could now be made considerably smaller than the previous prototype. In addition the reformer has been demonstrated on a variety of fuels including methane, methanol, ethanol, propane, butane, isooctane, and a benchmark fuel mix intended to simulate a sulfur-free gasoline. The development effort is being funded by the U.S. Department of Energy's Office of Transportation Technology.
