Stainless engine plates for Fuel Cells
The strip is generally cold rolled down to a thickness of 0,10 mm or even 0,075 mm, into a bright annealed state. This is necessary to mold the plate surface for creating a channel of different geometry, necessary to enable the deep diffusion of hydrogen and consequently the release of electrons that generate the electricity for the vehicle engines. The channel plate enables also the combination of hydrogen with oxygen in the air creating as only exhaust product, simply water.
