PURPOSE: A perovskite is provided to use another metallizing process which is cheap and is less complex by avoiding a chemical segregation in coating. CONSTITUTION: The perovskite is supplied for coating the inter-connector used in a high temperature fuel cell and its' structure can be a formula ABO¬3-E having A=(E¬I-W Ln¬W-δ) and B=(G¬I-ZJ¬Z). In the formula, E is a alkaline earth metal and desirably is a strontium or calcium while Ln is in lanthanide class. J is a second transition metal and desirably is Co, and W is a number which is more than 0.5 and is less than 0.5 and desirably is 0.2. δ is a negative or a positive number and its' absolute figure is about under 0.02. Z is more than 0.01 and is less than 0.5 and desirably is 0.2. Lastly, E is a positive or a negative number and its' absolute figure is about under 0.5. |
