Effect of flow geometry on anode-supported single chamber SOFCs arrayed as V-shape

摘要

The flow geometry of a single chamber solid oxide fuel cell was studied in order to reduce the effect of cell distance in the anode-facing-cathode stack. V-shape and converse V-shape configuration micro stacks consisting of two anode-supported yttria-stabilized zirconia membrane fuel cells were fabricated. The flow geometry reduced the effect of cell distance and improved the uniformity of performance of single cells in both stacks. The converse V-shape configuration was beneficial for maintaining the heat and the gases, in particular at low flow rates; the performance of the converse V-shape stack was better than that of the V-shape stack.
