- SOFCs Solid oxide fuel cells
- SOFC's system is mainly composed of two parts. It is divided into a member and a stack, and the member consists of a part exposed to high temperatures and a part not. At this time, it is experiencing great difficulties in commercialization due to deterioration of stack performance due to by-products generated from gas piping components exposed to high temperature environments, that is, hot BOP.
- BOP mainly uses SUS parts containing chromium and iron.
- chromium is included, chromium is volatilized from the BOP and adsorbed to the surface of the SOFC cell when high-pressure gas is introduced in a high-temperature environment. This leads to chromium poisoning at the cathode, blocking the catalytic reaction site on the electrode surface, or reacting with the perovskite structure electrode to form a non-conductive secondary phase, thereby accelerating the performance degradation of the electrode.
- wet powder spraying is a simple technology that applies a coating layer to the surface by mixing and spraying a coating material, binder, and solvent.
- wet powder spraying has disadvantages in that the amount of material used for introducing the coating layer is high and it is difficult to control the uniformity and quantitative control of the coating layer.
- the present inventors studied various examples of coating layers and their methods to suppress the chromium volatilization of BOP. As will be described later, a plating method that allows uniform deposition on a three-dimensional structure in a small amount in a short time was used.

Specifically, deposition was carried out under deposition conditions of -1.1 V, total deposition charge of 4.0 C, and about 20 minutes, and it was confirmed that a stable La 2 O 3 oxide was coated on the surface. All deposition processes were performed at room temperature (23° C.) and atmospheric pressure (1 atm).
