A method for processing separate fluid flows in a micro component system for the production of hydrogen gas used in fuel cells in which a first fluid flow is directed to micro channels formed on one side of a conductive separator maintained in an enclosure, a second fluid flow is directed to micro channels formed on the opposite side of the separator, and laminar flow is maintained in the fluids such that heat transfer between the fluids on the opposite sides of the micro channels is by conduction through the separator and heat transfer within the fluids on the opposite sides of the micro channels is predominantly by convection within the fluids.
