COMPONENTS AND METHODS FOR MANUFACTURE AND ASSEMBLY OF A FUEL CELL STACK

摘要

A fuel cell stack which is amenable to simple manufacturing processes and is thermally and mechanically compliant. The fuel cell stack reduces the number of components by combing fuel cell tubes to form tube sub-assemblies, the tube sub-assemblies comprising end fittings connected to the fuel cell tubes, the end fittings provided with at least one or preferably a plurality of channels to provide equal distribution of fuel throughout the fuel cell tubes.

1. A solid oxide fuel cell stack comprising of at least one fuel cell strip, each strip comprising a plurality of bundles, each bundle comprising a plurality of tube sub-assemblies, each tube sub-assembly comprising a fuel cell tube, each fuel cell tube having at least one passage extending longitudinally through the fuel cell tube, adjacent tube sub-assemblies being arranged substantially parallel and spaced apart, at least one end of each tube sub-assembly being connected to an end of an adjacent tube sub-assembly via at least one end fitting, wherein the at least one end fitting comprises at least one channel.
