Bipolar plates
We offer market-leading chemical etching services for bipolar plates, working with leading battery energy suppliers to develop etched bipolar plates for fuel cell stacks.
What is a fuel cell bipolar plate?
Fuel cells are produced by stacking precise and complex bipolar plates machined with intricate channels that allow liquids and gases to flow.
While CNC machining, stamping and hydroforming can be used to produce these channels, traditional metal machining has limitations such as affecting flatness (flatness) and introducing stress and burrs.
