Chromlok™ System

The ChromLok™ system fromfuelcell欧洲杯足球竞彩is an innovative technology that provides high-temperature protection to metallic parts used in solid-oxide fuel cell systems. TheChromLok™ system有很多互补的氧化物涂层设计prevent the discharge of harmful chromium species from stainless steels when heated at high temperature.

Manganese cobalite (MCO) coating(Figures 6 and 7) is one of the coating systems offered byfuelcell欧洲杯足球竞彩, featuring superior protection and low resistance qualities. These qualities make it suitable for cathode active-areas that demand electrical conductivity. Additional coatings such as non-active, insulating coatings are compatible with a Ni-based anode side coating and common seal materials.
