    • The present invention relates to a method for preventing cathode positioning of a solid oxide fuel cell assembly including an interconnect which connects the solid oxide fuel cell consisting of a cathode, an electrolyte and an anode in serial connection, comprising the step of coating the cathode with chromium prevention materials by oxidizing the chromium prevention materials with air received in the cathode. According to the present invention, a three phase boundary of the cathode is deposited and coated with jewellery such as silver and white gold steamed by air which is received during the operation of the solid oxide fuel cell. The deposition mechanism of the silver and the white gold is identical to the chromium poisoning mechanism, which prevents chromium poisoning by firstly depositing the silver and the white gold on the three phase boundary leading to the prevention of the a small amount of chromium poisoning from stainless steel used in solid oxide fuel cell stacks (SOFC).
    • 本发明涉及一种用于防止固体氧化物燃料电池组件的阴极定位的方法,该固体氧化物燃料电池组件包括将由阴极,电解质和阳极组成的固体氧化物燃料电池串联连接的互连件,包括以下步骤: 通过在阴极中接收的空气氧化防锈材料来防止铬防止材料。 根据本发明,阴极的三相边界被沉积并涂覆有诸如由固体氧化物燃料电池操作期间接收的空气蒸汽的银和白金等首饰。 银和白金的沉积机理与铬中毒机制相同,通过首先在三相边界上沉积银和白金,防止铬中毒,从而防止少量铬不良的中毒 用于固体氧化物燃料电池堆(SOFC)的钢。
