Abstract

Light reactive deposition can be adapted effectively for the deposition of one or more electrochemical cell components. In particular, electrodes, electrolytes, electrical interconnects can be deposited form a reactive flow. In some embodiments, the reactive flow comprises a reactant stream that intersects a light beam to drive a reaction within a light reactive zone to produce product that is deposited on a substrate. The approach is extremely versatile for the production of a range of compositions that are useful in electrochemical cells and fuel cell, in particular. The properties of the materials, including the density and porosity can be adjusted based on the deposition properties and any subsequent processing including, for example, heat treatments.
