International Classification:

H01M 2/20
H01M 8/24
H01M 2/08
H01M 2/14

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.

B05D 5/12

US Classification:

429036000, 427115000

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.

International Classification:

C01B 3/36
B01D 53/047
C01B 3/56
C10L 3/10

Abstract:

An improved hydrogen generation system and method for using the same are provided. The system includes an HDS unit configured to remove sulfur from a process gas and a fuel gas, a pre-reformer configured to convert heavy hydrocarbons in the process gas and the fuel gas to methane, a first heat exchanger configured to dry the pre-reformed fuel gas, a second heat exchanger configured to heat the dry pre-reformed fuel gas, and a reformer configured to produce a syngas and flue gas.

Abstract:

An improved hydrogen generation system and method for using the same are provided. The system includes an HDS unit configured to remove sulfur, a first and second pre-reformers configured to pre-reform a process gas and fuel gas, respectively, a first and second heat exchangers configured to dry and heat the pre-reformed fuel gas, respectively, and a reformer configured to produce a syngas and flue gas. The method includes using a process stream selected from the group consisting of air, PSA off-gas, hydrocarbon gas, and combinations thereof to dry the fuel gas and using a process stream selected from the group consisting of the flue gas, the syngas, and combinations thereof to heat the dry fuel gas. The second pre-reformer is a low-pressure pre-reformer, so that the heat contents of the fuel gas is increased through converting heavy hydrocarbons in the fuel gas to CO and Hby the second pre-reformer.
