In this paper, the performance of a radial flow reformer is analyzed. Fundamental principles of reaction engineering are utilized to design this reactor where methane is reformed to produce sufficient hydrogen to generate 20 W of power in a fuel cell. It is shown that the radial flow geometry leads to modest pressure drop. The reactor operates at a pressure of 150 kPa, a steam to methane ratio of 3 and an inlet temperature of 848 K and is able to generate sufficient hydrogen for 20 W of power. The heat duty required for the reformer is approximately 43% of the power generated. (C) 2009 Elsevier B.V. All rights reserved.
