Fuel cell plates
Precision Micro has long-standing partnerships with a number of leading alternative energy providers who benefit from economic, accurate, burr- and stress-free photo etched fuel cell plates.
Heater elements
Precision Micro is the world’s leading supplier of ultra-thin chemically etched resistive heating elements used in a wide range of energy applications.
Heat exchangers
Complex channels and geometries can be photo etched onto individual heat exchanger plates economically, maximising thermal efficiency.
Meshes, filters and sieves
Where punch-perforated sheets are prone to distortion, photo etched mesh is burr- and stress-free, with zero material degradation.

In partnering with the world’s leading green and renewable energy providers, Precision Micro’s pioneering photochemical etching process is being used as an enabling technology for several exciting sustainability projects.
Some of these projects include:
- Fuel cells and electrolysers for hydrogen production, storage and delivery
- Printed circuit heat exchangers for more efficient heat transfer
- Electro-thermal ice protection systems for aircraft
- Busbar battery interconnects for electric vehicles
- Motor laminations for electric flight
Precision on a micro-scale
Our chemical etching service offers consistent precision over both large and small surface areas.
For example, resistive heating elements used in aircraft electro-thermal ice protection systems are photo-etched to extremely tight resistance tolerances in lengths up to 1500mm. This solution cuts the energy typically consumed by a bleed air system by up to 50%.
Likewise, our chemically etched bipolar plates used in hydrogen fuel cells and electrolysers can be made thinner, stronger and burr- and stress-free with complex channels down to 0.020mm.
Standard and specialist materials
We work with both standard and specialist metals where high strength-to-weight ratios, corrosion resistance or low coefficient of thermal expansion are required.
As there is no thermal cycle when metal is processed using chemical etching. Complex features and geometries can be photo-etched simultaneously to maximise efficiency and reduce costly post-process operations.
Added value technologies for single-source supply
We offer a wide range of added value technologies to help streamline supply, such as diffusion bonding, brazing and more.
