SBIR-STTR Award

This Small Business Innovation Research (SBIR) Phase I project addresses proton exchange membrane (PEM) fuel cells for the Partnership for a Next Generation of Vehicles (PNGV) program. Automobiles capable of 80 miles per gallon (or the energy equivalent) and a range of 300 miles are sought at a cost that would be acceptable to typical American automobile buyers. PEM fuel cells may provide the power source if a practical method can be found for on-board conversion of liquid hydrocarbon fuels to a hydrogen fuel which these fuel cells can use. Presently available technology for converting hydrocarbon fuels to hydrogen is steam reforming. This process is unsuited to use on board a vehicle for two reasons. First, the steam reforming reaction is endothermic, meaning that heat must be generated and transferred to the steam reforming reactor, which is complex and cumbersome for on-board use. Second, the hydrogen produced by steam reforming contains large amounts of CO and carbon dioxide and cannot be used in fuel cells without extensive purification. Such purification is also complex and cumbersome for on-board use. The technology under study in this SBIR project produces hydrogen via a modified steam reforming reaction. This modified reaction is mildly exothermic, obviating the need to supply heat to the reactor, and it produces hydrogen with high purity. Thus, many of the problems of conventional steam reforming may be avoided. Phase I will include a series of experiments which will provide bench scale proof of concept for the application of the concept to on-board hydrogen generation.
