Latest Patent Applications

Jaakko Niinistö has submitted a patent application for a method for producing a SOFC cathode diffusion barrier layer. This invention provides an improved method for producing the cathode diffusion barrier layer and a SOFC with high efficiency and longevity. The process involves depositing a pure ceria or aliovalently doped ceria layer by atomic layer deposition (ALD) on the electrolyte layer of the sintered half cell. The surface of the electrolyte is exposed to a dose of vapor from one or more lanthanide first precursors, followed by the removal of any excess unreacted vapor. A vapor dose of the second precursor is then introduced to the surface and allowed to react. A second purge completes the ALD cycle, which is repeated to build up thicker films. This ceria layer forms a cathode diffusion barrier layer, on top of which a cobaltite-based cathode layer is applied by screen printing. The cathode diffusion barrier layer and cathode layer are then heated together to form a SOFC.

Conclusion

Jaakko Niinistö's contributions to SOFC technology through his innovative methods highlight the potential for advancements in energy efficiency and longevity. His work at Elcogen AS positions him as a significant figure in the field of fuel cell technology.
