An experimental study of steam methane reforming in a microchannel is presented. Palladium nanoparticles, deposited on a porous aluminized FeCrAlY felt, served as catalyst sites for the reforming reactions. Parametric studies of steam-methane ratio, residence time, average reactor temperature, and temperature distribution were performed. Results demonstrated in excess 60 percent conversion of methane at an average reactor temperature of 900°C and the lowest experimented residence time of 26 milliseconds. Methane conversion was found to be strongly dependent on reactor temperature. Ramping temperature distributions demonstrated a 46 percent greater hydrogen output than isothermal reactions performed at the same average temperature.
