In the present study, surface catalytic reaction in a micro-channel with non-reactive hydrogen-air flow is investigated. Here, the micro-channel wall is coated with a catalyst. A solution to catalytic micro-channel flow is gained by applying an iterative method to solve the energy, mole fraction, and catalytic reaction equations. To validate the model, the results of fuel conversion are compared with results of experimental studies available in literature and good agreement between them is achieved. Moreover, the results show that increasing hydraulic diameter of micro-channel decreases normalized temperature of the mixture and catalyst heat transfer. Steeper variations are observed in the case of dh/L<0.2. Furthermore, when wall to inlet temperature ratio is smaller than 2.5, the fuel conversion is very small and for TW/Ti>3.5, the fuel is fully converted.
