Photochemically-etched anodes and cathodes for high volume applications

Photofabrication Engineering Inc (PEI) has a line of custom-made photochemically-etched anodes and cathodes for fuel cells, heat exchangers, oxygen and hydrogen generators. These products have applications in the aerospace, automotive , biotechnology, medical, appliances, power and electrical/electronic industries.

PEI, using a proprietary process can photoetch pure titanium, titanium alloys, zirconium and zirconium alloys along with more standard materials such as aluminium, stainless steel, copper and brass.

It has the unique ability to photoetch lightweight parts from exotic materials in production quantities which according to PEI allows manufacturers to meet high-volume, low-cost manufacturing goals, accelerating the commmercial viability of fuel cells, heat exchangers and oxygen and hydrogen generators.

Parts may be etched in thicknesses from 0.0127 to 2.286 mm.

The photoetching process creates parts that are smooth and free of the burrs and stresses associated with other manufacturing processes. Because of the broad range of materials that can etch., PEI can produce anodes and cathodes that are resistant to corrosion and high heat, and that can be friction-bonded, brazed or welded. Photochemical etching provides greater tolerance control for elaborate parts, and can provide intricately-shaped parts.

The manufacturing process has achieved ISO-9002 certification and complies with most customer and the military standards.
