The electrodeposition of ceramic and organoceramic films for fuel cells

The electrodeposition of metals from aqueous solutions is a longstanding te chnique, commonly known as electroplating. Now, electrodeposition is being used to produce ceramic coatings. Two such processes are known as electroly tic and electrophoretic deposition. They may be applied to protective coati ngs, biomedical implants, electronic devices, chemical sensors, piezoelectr ic transducers, displays, and electrode materials. Electrodeposition offers important processing advantages and allows new possibilities in the design of materials and devices. This paper describes recent developments in the application of electrodeposition for fabrication of fuel cell membranes.
