Influence of Airborne-salt on Performance of Solid Oxide Fuel Cell

Abstract

Fuel cells have worldwide impact as a new means of highly efficient and clean power generation, and they also have the possibility of application to the transports. We have researched on some problems of the solid oxide fuel cell (SOFC) applied to the power generation source for the ship in the future. The aim of this study is to make clear the influence of airborne-salt on the cell performance.
The experiment was carried out with a small scale planner type SOFC in which the working air was accompanied with salted mist. As a result, a cell performance was not inferior to that in the case without salt, and rather showed some increasing tendency than that. It was also found that the inlet airborne-salt penetrated into the air-electrode but not into the electrolyte. In order to find out the cause for improvement in the cell performance, the behavior of the salt into the air-electrode was investigated and discussed.
