Substrate selection

Essential to PEMFC stack operation.

Current collection and distribution

Connects adjacent cells and distributes current across the active area to support consistent electrical performance throughout the stack.

Reactant distribution and water removal

Etched channels distribute hydrogen and air across the active area while providing controlled pathways for product-water removal.

Heat transfer, compression and sealing

Supports heat distribution, stack clamping and repeatable sealing while preserving the intended flow-field geometry.

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
