In some embodiments of the present invention, methods of using one or more small spot showerhead apparatus to deposit materials using CVD, PECVD, ALD, or PEALD on small spots in a site isolated, combinatorial manner are described. The present invention can serve a wide variety of useful purposes, such as a greeting device, advertising premium, fundraising device, souvenir, business gift, and a stress reduction product. Analysis is conducted as to whether program data for the different time units can fit in the portions of memory and adjustments to the amount of program data for respective time units are made. The inlet air stream may be the cathode exhaust stream of the fuel cell, and the inlet fuel stream may be input hydrocarbon fuel that is directed to the reformer to produce hydrogen-rich reformate.
