Solid oxide fuel cell interconnects are typically chromium alloys that function well under high temperature operation but have one major disadvantage, i.e., the formation of volatile chromium oxide species that are deleterious to fuel cell operation, an effect commonly known as chromium poisoning. To date, Gates Canada has treated the problem by applying a barrier layer of conductive ceramic by plasma spray. The LaMnO3 ceramic is a relatively high cost material, and the plasma spray process and required equipment also have high associated costs.

固体氧化物燃料电池互连件通常是铬合金，其在高温操作下运行良好，但具有一个主要缺点，即，形成对燃料电池工作有害的挥发性氧化铬物质，这种效应通常称为铬中毒。到目前为止，加拿大盖茨公司已经通过等离子喷涂施加导电陶瓷阻挡层来处理这个问题。LaMnO3陶瓷是相对高成本的材料，并且等离子体喷涂工艺和所需设备也具有高的相关成本。
