Steel substrates

Etching + CNC

Flow-field manufacturing

Essential to AEM stack operation.

 Current collection and distribution

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

 Water and gas management

Engineered flow fields guide water through the active area and support efficient removal of hydrogen and oxygen from the reaction zones.

 Structural support and surface protection

The steel plate supports stack clamping and sealing, while the nickel-plated surface provides conductive corrosion protection in alkaline operating conditions.

How the routes compare.

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 cutting 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
