The process

What is chemical etching?

Chemical etching, also known as photo etching or metal etching, is a highly precise, tightly controlled corrosion process used to produce complex metal components with very fine detail.

Unlike traditional sheet metalworking, no mechanical force or heat is used during the chemical etching process. This means material properties are unaltered and etched components are free from stresses and burrs.

Bipolar fuel cell plate

Bipolar plate manufacture: Why fuel cell engineers should consider chemical etching

Fuel cells are produced by stacking precise and intricate plates machined with complex grooves or channels and can be variously manufactured using CNC-machining, hydroforming and stamping, but there are question marks over the scalability and capability of these processes.
