Research Abstract |
Among several types of fuel cells, a solid oxide fuel cell (SOFC) can provide the highest efficiency and have many kinds of cell geometries. In this study, we focused on a disk shape planar-type SOFC and proposed a technique effective for improvement of the disk shape SOFC performance through experiments by using model channels. A non-uniform temperature distribution inside the SOFC causes large thermal stresses, which is one of the hurdles in commercializing SOFCs. To overcome this drawback, we designed a new channel with circle involute shape current collectors having a narrow gap between adjacent them. By using this channel, we demonstrated that a swirling flow was generated in the channel and its velocity distribution along the channel width direction was almost similar shape in the whole region of the channel. We also investigated characteristics of heat transfer in the present channel and found that this channel structure was suited to SOFC from Nusselt number distributions.
