Surface Chemistry Effects in Finite Element Modeling of Heat Transfer in µ-fuel Cells

Authors: M.A. Havstad

Affilation: Lawrence Livermore National Laboratory, United States

Pages: 310 - 313

Keywords: microreactor, heat transfer, surface kinetics

Abstract:
Equations for modeling surface chemical kinetics by the interaction of gaseous and surface species are presented. The formulation is embedded in a finite element heat transfer code and an ordinary differential equation package is used to solve the surface system of chemical kinetic equtions for each iteration within the heat transfer solver. The method is applied to a flow which includes methane and methanol in a mecroreactor on a chip. A simpler more conventional method, a plug flow reactor model, is then applied to a similar problem. Initial results for steam reforming of methanol are given.
