Abstract

A fuel cell stack module includes a plurality of fuel cell stacks, a base supporting the plurality of fuel cell stacks, and a metal shell located over the base and the fuel cell stacks. The metal shell contains an integrated heat exchanger.

First claim

What is claimed is:

1. A fuel cell stack module, comprising:
a shell having a plurality of doors;
a support disposed inside the shell and having a vertical mounting surface; and
a plurality of solid oxide fuel cell stacks horizontally mounted on the vertical mounting surface of the support in vertically separated layers inside the shell such that the plurality of horizontally mounted fuel cell stacks have a stacking direction that extends perpendicular to a major surface of one of the plurality of doors.

2. The module of claim 1 , wherein the solid oxide fuel cell stacks are mounted on the support using one or more rails.

3. The module of claim 1 , wherein the support comprises a central column having the mounting surface and containing an integrated heat exchanger.

4. The module of claim 3 , wherein the plurality of solid oxide fuel cell stacks comprise an annular array of internally manifolded solid oxide fuel cell stacks surrounding a central axis in the central column.
