Printed circuit board and/or semiconductor wafer fabrication techniques and technologies are applied to create anode and cathode electrodes for exothermic reaction chambers and processes. Starting with an appropriate substrate, e.g., ceramic, anodes and cathodes of varying shapes and spaced relationships, formed of the reactive materials required, may be fabricated on the same or different layers as conductive traces. In some embodiments, the shapes and placement of the traces, and use of one or more ground planes, may optimize the generation of magnetic fields as current passes through the traces. In some embodiments, an iron core may shape and/or enhance the strength of magnetic fields. In general, the use of PCB/IC fabrication technology allows the manufacture of electrodes for exothermic reactions that are rugged, made from appropriate materials, and have known and repeatable impedances, spaced relationships, magnetic coupling, and other properties.
