Application: Binder jet printing of metallic interconnect for solid oxide electrochemical cell stack (Patent ID: US20240139810A1)
The patent filed by Bloom Energy Corp. describes a method for manufacturing metal alloy interconnects for electrochemical stacks using binder jet printing, debinding, and sintering processes. The method involves depositing a metal alloy powder on a printer bed, applying a binder in a predetermined pattern, drying the binder, and repeating the process multiple times to form a green interconnect. The resulting metal alloy interconnect can be used in solid oxide fuel cell stacks or solid oxide electrolyzer cell stacks, and can be further integrated into fuel cell systems or electrolyzer systems.
The metal alloy powder used in the process can be a pre-alloyed chromium iron alloy powder or a ferritic alloy, such as ferritic stainless steel. The resulting metal alloy interconnects can have specific compositions, such as containing 11 to 30 wt. % Cr and 70 to 89 wt. % Fe for ferritic stainless steel interconnects. The interconnects can feature fuel-side ribs, air-side ribs, fuel channels, air channels, fuel inlet holes, and fuel outlet holes, providing a versatile solution for various electrochemical stack configurations. Overall, the method offers a cost-effective and efficient way to produce high-quality metal alloy interconnects for electrochemical applications.
