PLANAR SOLID OXIDE FUEL CELL STACK AND ITS INTERCONNECT THEREOF

摘要

A planar solid oxide fuel cell stack which can expand in both the vertical and horizontal directions is disclosed. The planar solid oxide fuel cell stack comprises an interconnect which consists of an interconnect body, a first flowing area and a second flowing area, wherein the first and the second flowing area are disposed on opposite side of the interconnect body, and have one gas inlet and two gas outlets, respectively. By employing multiple hexagonal interconnects for cell stack expanding in the horizontal direction, each three stacks can share the same pipeline of the flow channel, thereby reaching the goals of reducing the space and materials required and system complexity as well.

主权项

1. An interconnect disposed between two solid oxide fuel cells for collecting current generated, comprising:
an interconnect body; a first flowing area, disposed on a first side of said interconnect body, wherein on one end of said first flowing area is a first gas inlet and on the other end of said first flowing area are two first gas outlets which connect with said first gas inlet; and a second flowing area, disposed on a second side of said interconnect body, wherein on one end of said second flowing area is a second gas inlet and on the other end of said second flowing area are two second gas outlets which connect with said second gas inlet, said second gas inlet is disposed between said two first gas outlets, and said first gas inlet is disposed between said two second gas outlets.
