Substrate selection

Essential to SOEC stack operation.

Electrical interconnection and current distribution

Connects adjacent cells and carries current through the stack while limiting resistive loss across repeated interfaces.

Steam and product-gas management

Etched flow fields distribute steam and reaction gases across the active area and provide controlled routes for product-gas removal.

Gas separation and structural support

Maintains separation between fuel- and oxygen-side streams while supporting sealing and plate geometry through high-temperature operation.

An at-a-glance process comparison for thin SOEC interconnects and evolving flow fields.

Engineering factor	YIANTENG etching	Stamping	Full CNC
Design changes	Update a digital phototool	Rework or replace the hard die	Revise program, fixture and toolpath
Prototype validation	Multiple variants can share one sheet	Production tooling precedes first parts	Each variant needs machining setup
Edge and stress	Burr- and stress-free	Burrs and forming stress may occur	Tool marks; deburring may be needed
Complex flow fields	All channels etched simultaneously	Complexity moves into die design	Features machined path by path
Cost profile	Low tooling; complexity has limited time impact	Higher upfront tooling; strong at stable high volume	Cost rises with setup and toolpath time
