Fuel cell column heat exchanger mated module

A fuel cell module (10) with a fuel cell column (18), having at least one fuel cell stack, mated with the planar wall of a heat exchanger (60), wherein the fuel cell column and heat exchanger are mounted to a support structure (30), and which define an air plenum between the fuel cell column and planar wall of the heat exchanger, thereby eliminating the ductwork and insulation requirements associated with heat exchange systems while increasing the efficiency of the heat exchanger.

High-performance ceramic interconnect for SOFC applications

An improved ceramic interconnect component for a solid oxide fuel cell having good electrical conductivity thermodynamic stability in the presence of fuel and a coefficient of thermal expansion matching closely that of zirconia electrolytes is disclosed. The interconnect is a lanthanum strontium chromate material containing minor quantities of calcia, and iron and, optionally, very minor quantities of cobalt, as dopants.
