The overall objective of the project is to investigate, design and test an improved steam reformer for fuel cell power plants. Catalytic combustion is used to minimise the disadvantages of conventional external reforming. By integrating various technologies, smaller-scale reformer, lower emission levels and reduced start-up time along with improved temperature control can be achieved. Catalytic combustion is used to generate the heat required for the reforming reaction, thus avoiding NOx formation. The heat can be generated locally and made available for the reforming reaction using a thermally conductive substrate. The first results of the catalytic test reactor show good conversion rates for both the combustion and the reforming reaction. Based on the hydrogen production rate, the initial objectives for the volume of the reformer have proven to be feasible. The results are used to build a 20 kW integrated test reactor.
