US Classification:

429510, 429468, 429469, 429508, 429509

Abstract:

A method of manufacturing a fuel cell stack is provided. The method provides forming an inspectable preassembly of multiple fuel cell assemblies that may be termed a pseudostack. Each fuel cell in the pseudostack has permanent electrical interconnections and sealing connections on only one of the two electrodes, namely an anode layer or a cathode layer. For example, an anode interconnect may be firmly attached to the anode layer by means of a bonding agent and a sealing agent used to seal passages on the anode layer of the fuel cell. Alternatively, seals and permanent electrical connections may be made on the cathode layer of the fuel cell, and not on the anode layer.

Abstract:

A fuel cell stack comprises multiple fuel cell assemblies, wherein each fuel cell assembly includes a fuel cell comprising an anode layer and a cathode layer, and an electrolyte interposed between the anode layer and the cathode layer. The fuel cell assembly further comprises an anode interconnect and a cathode interconnect, wherein the anode interconnect may be firmly attached to the anode layer by means of a bonding agent and a sealing agent used to seal passages on the anode layer of each fuel cell.
