Abstract: Disclosed is a method of forming a high performance, electrochemical components. The plate is manufactured by forming a first electrode material on a substrate. Next, a thin electrolyte or interconnector coating is deposited on the electrode material. In the final step, a second electrode material is deposited on the electrolyte or interconnector, and the complete structure is removed from the substrate. The electrolyte/electrodes plates and interconnector plates formed by the method of this invention may be used in the manufacture of electrochemical converters.
