Abstract:
1. A method for coating a fuel cell plate, the method comprising the steps of: providing the fuel cell plate having inlet apertures, outlet apertures, and a plurality of flow channels; providing an atmospheric pressure air plasma (APAP) device, the APAP device generating a plasma jet from an ionizing gas including at least one of air, nitrogen, oxygen, and an inert gas, the APAP device including a voltage supply for supplying voltage to an electrode of the APAP device, wherein the voltage supplied to the electrode is between 130 V and 150 V, and the APAP device further including a plasma nozzle for projecting the plasma jet from the APAP device; and delivering the plasma jet to a surface of the fuel cell plate, wherein a silicon-containing coating is formed on the surface of the fuel cell plate by the plasma jet from the APAP device.
