Abstract

The present invention is concerned with improved fuel cell stack assemblies, and methods of operation of a fuel cell stack assembly, particularly with improved gas flow and thermal management.

Description

technical field [0001] The present invention relates to improved fuel cell stack assemblies and methods of operating fuel cell stack assemblies, particularly to improved airflow and thermal management. Background technique [0002] The term "fuel cell stack assembly" as used herein means at least one fuel cell stack each comprising at least one fuel cell stack layer and a fuel cell for one or more fuel and oxidant streams used a stack floor and a cover sealingly connected to the fuel cell stack floor, at least one gas inlet into the cover volume, and a preheater (not located in the cover volume), wherein at least one fuel cell stack layer each includes at least one A fuel cell, fuel and oxidant inlet / outlet connections, and flow paths for one or more fuel and oxidant streams define a shroud volume between the fuel cell stack base plate and the shroud. Other optional components of the fuel cell stack assembly suitably include fuel side seal assemblies, oxidant side seal asse...
