Influence of structure size on voltage uniformity of flat tubular segmented-in-series solid oxide fuel cell

In the present work, a two-dimensional model is used to evaluate the voltage distribution of a flat tube segmented-in-series solid oxide fuel cell (FTS-SOFC) including a fuel channel, an anode, a cathode and an electrolyte layer. The results indicate that when the other cell dimensions are fixed, th...

Description
Summary:In the present work, a two-dimensional model is used to evaluate the voltage distribution of a flat tube segmented-in-series solid oxide fuel cell (FTS-SOFC) including a fuel channel, an anode, a cathode and an electrolyte layer. The results indicate that when the other cell dimensions are fixed, the anode length of 5 mm gives the highest maximum power density for the FTS-SOFC. By changing the anode length of single cell of FTS-SOFC, the voltage uniformity can be significantly improved, which avoids the low voltage of single cell in the downstream, and provides effective design suggestions for the development and industrialization of FTS-SOFC. [Display omitted] •A 2D model has been developed for flat tube segmented-in-series SOFC.•When the anode length is 5 mm, the maximum power density of FTS-SOFC is achieved.•Changing anode length of FTS-SOFC can significantly improve voltage uniformity.
