Process to prepare a hydrogen rich gas mixture from a halogen containing gas mixture comprising hydrogen and at least 50 vol. At least one of the first and second electrodes includes a platinum-containing layer. The polyimide layer has a thickness of less than about 50 microns, and a cleaning surface shaped to match a contour of the support surface. An electrical panel controls operations of the lamp bank and the temperature control unit, such that an environment within the environment recreation laboratory may very closely simulate the environment under real sunlight. The node processor operates a first energy consuming device to maintain a first local environment.
