Arrangement of components in a solid oxide fuel cell and manufacturing method thereof

摘要

Described herein are solid oxide fuel cells and manufacturing methods thereof. In certain aspects, the solid oxide fuel cells described herein include a plurality of anodes and a plurality of cathodes in which the anodes and cathodes are alternately stacked on each other and have non-overlapping sections in which the anodes and cathodes do not overlap partially. In certain aspects, the plurality of anodes are electrically connected to a first electrode, and the plurality of cathodes are electrically connected to a second electrode. In certain aspects, a solid electrolyte can be included, for example, between the anode and the cathode. In certain aspects, partitioning sections are disposed between each of the cathodes and the first electrode and between each of the anodes and the second electrode.

1. A solid oxide fuel cell, comprising:
a plurality of solid electrolytes; a plurality of anodes sandwiched by each of the plurality of solid electrolytes and a plurality of cathodes sandwiched by each of the plurality of solid electrolytes, the plurality of anodes and the plurality of cathodes being alternately stacked on each other in a stacked direction, and a plurality of first partitioning sections sandwiched by each of the plurality of solid electrolytes and a plurality of second partitioning sections sandwiched by each of the plurality of solid electrolytes, the plurality of first and second of partitioning sections being alternately stacked on each other in the stacked direction and being staggered in a direction perpendicular to the stacked direction, wherein each of the plurality of anodes has one end exposed and another end contacting a corresponding first partitioning section in the direction perpendicular to the stacked direction, each of the plurality of cathodes has one end contacting a corresponding second partitioning section and another end exposed in the direction perpendicular to the stacked direction, fuel is supplied from the exposed one ends of the plurality of anodes towards the another ends of the plurality of anodes, air is supplied from the exposed another ends of the plurality of cathodes towards the one ends of the plurality of cathodes, and the supplying directions of the fuel and air are opposed to each other so that the fuel and air flow countercurrent to each other throughout the solid oxide fuel cell.
