Bipolar plates, fuel cells

In order to reduce CO2 emissions from vehicles, various alternative drive systems are being developed. One of them is the fuel cell, which generates energy through a chemical reaction between hydrogen and oxygen, producing only water as a by-product.
Compared to the conventional combustion engine, the fuel cell has much higher requirements for the compression and supply of air. Air must be completely particle-free at a constant pressure level in order to increase the longevity of the sensitive fuel cell.
Thanks to our precision and the ability to etch the finest geometries, we can produce metal filters that mean you no longer have to worry about particles in the fuel cell.
